P4 :
Define what is meant by the rate of a chemical reaction.
State two ways in which you can increase the rate of a reaction between a solid and a
gas.
Explain how increasing the temperature affects both the rate of reaction and the
position of equilibrium in a reversible reaction.
A catalyst is used in a reaction. Explain how it increases the rate of the reaction
without affecting the position of equilibrium.
In the reaction between nitrogen and hydrogen to form ammonia, how would
decreasing the temperature affect the yield of ammonia?
