chemistry - reaction kinetics

Question 1

what is the definition of the rate of reaction?

Answer 1

the rate of a reaction is defined as the change in concentration of a reactant or a product per unit time

Question 2

what is the definition of the rate equation?

Answer 2

the rate equation is a mathematical equation that shows how the rate of reaction is dependent on the concentration of the reactants

Question 3

what is the definition of the order of reaction?

Answer 3

1. the order of reaction with respect to a reactant is the power to which the concentration of that reactant is raised to in the rate law
2. the overall order of reaction is the sum of the powers to which the concentrations of the reactants are raised to in the rate law

Question 4

what is the definition of the half life of a reaction?

Answer 4

the half life of a reaction is the time taken for the concentration of a reactant to decrease to half its initial value

Question 5

what does the collision theory state?

Answer 5

the collision theory states that to react, the reactant particles must collide with sufficient energy with the correct orientation, producing effective collisions which will result in product formation

Question 6

what is the definition of activation energy?

Answer 6

the activation energy of a reaction is the energy barrier the reactants must overcome in order to become the products
