Physical Chemistry 2)c) - Kinetics

Question 1

what is kinetics?

Answer 1

the study of factors which alter the rates of chemical reactions

Question 2

what is zero order?

Answer 2

when changing the concentration of the reactant has no effect on the rate of reaction

Question 3

what is the order when doubling the concentration of A doubles the rate of reaction?

Answer 3

first order

Question 4

what is the order when doubling the concentration of A quadruples the rate of reaction?

Answer 4

second order

Question 5

how can you find the overall order of a reaction?

Answer 5

the sum of the powers to which the concentrations of the reactants are raised in the rate equation

Question 6

what is meant by the rate determining step?

Answer 6

the slowest step in the reaction which controls the overall reaction rate
