1
Q
Rate of reaction =
A
Change in conc. / time
2
Q
Define rate of reaction
A
The change in concentration in unit time of any one reactant or product
3
Q

Nature of reactants ie ionic or covalent
Catalyst
5
Q
Define catalyst
A
A catalyst is a substance that alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction
