Does the overall energy ever change?
137-144

Understanding energy changes in reactions

 

•  How do chemists try to understand these energy exchanges?

•  What are the key terms used?

Define them?
141-142

Understanding energy changes in reactions

•  Calculate the theoretical energy change in a reaction

Calculate the practical energy change in a reaction carrying out all the measurements
142-144
Use the energy changes to develop trend data and calculate/ estimate unknown energy change

Introduce the term rate

•  What is rate?

•  What are the factors that affect it?

Why?
124-136

Effect of surface area on rate

What happens to particles/

•  How does it show on graphs?

•  How to you interpret the graphs?

•  What does the gradient at any point tell you?

What is happening in terms of particles at that point?

Follow rate using different concentrations of acid

•  What happens

•  Why?

Discuss in terms of particles.

•  How does it show on graphs?

•  How to you interpret the graphs?

•  What does the gradient at any point tell you?

What is happening in terms of particles at that point?

Follow rate using different temperatures of thiosulphate acid

•  What happens

•  Why?

Discuss in terms of particles.

Follow rate using different catalysts on H2O2

•  What happens?

•  Why?

•  Discuss in terms of particles.

Industrial chemistry and reversible reactions

Understand the terms equilibria and its importance in industry

Why is it important to influence reactions to produce more/less of products?

What factors can influence equilibria?

Why do they do so?

What is the reason behind how they do so?

Manufacture of ammonia, nitric acid and sulphuric acid.

145-155
Review understanding equations learnt in year 9 52-53

Understand the new unit mole that chemists use

Why is it necessary?

Learn how to use moles to equate different substances in terms of particles as it is particles that react.

Learn how to calculate from formulae and percentage composition.

Learn how to get formulae from reacting masses.

Learning volumes of gases

54-78
