PLEASE REMEMBER, THESE ARE NOT 'STAND ALONE' NOTES, and were designed for my classes for use alongside the Salters resources - Chemical Ideas, Chemical Storylines, Practical Activities-Investigations and the AS-A2 Revision guides all published by Heinemann Secondary Series, to reduce the reading workload and offer a study strategy. From your teacher (not me!), its handy to have the answers to the Chemical Ideas, Storylines Assignments and Activities Questions side by side with the texts and these strategy pages. You haven't time to redo the Q's but a quick read of the Q's and connecting with the official answers is valuable revision - there is too much hit and miss revision from doing past papers in my opinion.

VCI 1 Introduction

The chemical industry is a major contributor to the quality of our lives and national economy.

Just look around your house from the kitchen to the bathroom!

Activity VCI 1 Your visit to the chemical industry

The idea is to appreciate as many of the ideas in CI 15.1 to CI 15.4, the value for final revision depends on what notes you made at the time!

Chemical Storylines VCI 2 Research and Development

Give it one thorough read with the learning objective list alongside you.
- Chemical and economic consideration list at the top right of p286
- research experiments => pilot plant => full production plant
  - All proceed by trial and error as much as theoretical planning.

Chemical Ideas 15.3 The best conditions for the process

Give it one thorough read with the learning objective list alongside you. You will encountered some of the ideas when studying the manufacture of ammonia by the Haber Process in unit AA.
- Most considerations boil down to rates of reaction and equilibrium factors and maybe balancing a low yield fast versus a high yield produced too slowly.

Chemical Storylines VCI 3 Building the Chemical plant

Give it one thorough read with the learning objective list alongside you.
- Lists of considerations given on right column of p287. Its all about picking up ideas.

Chemical Ideas 15.1 The operation of a chemical manufacturing process

Give it one thorough read with the learning objective list alongside you. You will encountered some of the ideas when studying the manufacture of ammonia by the Haber Process in unit AA.
- Batch versus continuous production.
- Plant construction materials - safety and economic factors involved.
- Rates and equilibrium factors.

Chemical Storylines VCI 4 People

Give it one thorough read with the learning objective list alongside you.
- Lots of different skills and services needed to run chemical factories.

Chemical Storylines VCI 5 Safety Matters

Give it one thorough read with the learning objective list alongside you. You will encountered some of the ideas when studying the transportation of bromine in unit M.
- Physics, chemistry and medical science all needed to take of all the health and safety issues involved in manufacturing chemicals.

Chemical Storylines VCI 6 Environmental Issues

Give it one thorough read with the learning objective list alongside you.
- What pollutants may be formed?
- Can they be reduced?
- How do we deal with them?
- What pollution levels are acceptable?
- Anti-pollution strategies involve extra cost.

Chemical Storylines VCI 7 Location

Give it one thorough read with the learning objective list alongside you.
- Strategic location near suitable raw materials with good transport links.
- Historically, the raw material site came first and the transport links developed later.
- Many raw materials now come from abroad, so the transport infra-structure becomes an even more important consideration e.g. coastal sites for oil refineries.

Activity VCI 7 Setting up a new chemical plant

Give it one thorough read with the learning objective list alongside you.

Chemical Storylines VCI 8 Choosing a feedstock

Give it one thorough read with the learning objective list alongside you.
- Cost of it? versus market demand for useful possible products from it?

Chemical Ideas 15.2 Feedstock's

Give it one thorough read with the learning objective list alongside you.
- Examples of feedstocks => products.
- Origin of feedstocks and their transportation.

Chemical Storylines VCI 9 Making a Profit

Give it one thorough read with the learning objective list alongside you.
- Everything thing has to come together to make a profit.

Chemical Ideas 15.4 Becoming even more efficient

Give it one thorough read with the learning objective list alongside you, think COSTS all the time!
- Recycling unreacted materials.
- Heat exchangers e.g. can you use the heat from an exothermic process?
- Can you find a use for co-products (2 or more useful products formed).
- Can you reduce or find a use for the formation of unwanted by-products?

Chemical Ideas 15.5 Costs

Give it one thorough read with the learning objective list alongside you.
- Know examples of production costs consisting of ...
  1. fixed costs - independent of production volume for market demand e.g.
    - plant depreciation
    - labour and telephone etc.
    - land purchase
  2. Know examples of variable costs - relate to units of production
    - variation in price of raw material
    - varying transport cost e.g. price of vehicle fuel
    - effluent treatment and disposal - rises with production rate.
- Know examples of capital costs - building the chemical plant and the associated infrastructure.
