Answer:
Addition of catalyst
Rate of reaction
Explanation:
A chemical reaction can be "sped up" by the addition of a catalyst. A catalyst speeds up the rate of a reaction by reducing the activation energy of the reaction. Activation energy is the minimum amount of energy required for a reaction to proceed. Thus, when this energy is reduced, the reactants can easily be converted into products as it becomes easier to overcome the normal activation energy of the reaction.
An increase in the reactants in a chemical reaction causes more products to be produced hence increasing the rate of the reaction. Rate of reaction is the amount of products formed by unit time of a reaction.
