Reaction Kinetics

Question 1

Define rate of reaction

Answer 1

How fast reactants are used up or products are formed.
Change in concentration of reactants or products per unit time.
Rate= change in concentration of reactants or products/ time
Unit= mol dm-³ s-¹

Question 2

Define effective/ successful collision

Answer 2

When the reactant particles have enough energy to react and change into product particles that is known as effective collision

Question 3

Define activation energy

Answer 3

Minimum amount of energy required for the reactants to start the reaction.

Question 4

Define catalyst

Answer 4

Any substance that alters the rate of a reaction
