What generally happens to rate of reaction as temperature increases?

Can changing the concentration of reactants alter the rate of reaction?

What is the role of a catalyst in a chemical reaction?

Which factors can increase the rate of a chemical reaction?

What happens to the rate of reaction when the surface area of a solid reactant is increased?

The rate of a reaction refers to how quickly reactants are used up or products are formed.

Which of the following are true about the rates of reactions at equilibrium?

Which graph correctly shows how rate of reaction changes with increasing temperature?

A catalyst lowers the activation energy of a reaction.

Which of these would increase the rate of a gas reaction?

What is meant by the term 'rate equation' in terms of rate of reaction?

All reactions proceed at the same rate under equivalent conditions.

What effect does a decrease in concentration have on the rate of reaction?

In a reaction diagram, what does the peak of the curve represent?

Pressure only affects the rate of reaction for reactions involving gases.
