Using the method of initial rates for the reaction a → b, if the initial concentration of a is doubled and the rate of reaction quadruples, what is the order of reaction with respect to a?
Answer is: reaction is second order with respect to a. This second order reaction is proportional to the square of the concentration of reactant a. rate of reaction = k[a]². k is second order rate constant and have unit M⁻¹·s⁻¹. Integrated rate law for this reaction: 1/[a]=1/[a]₀ + kt. t is time in seconds..
