Select the correct answer.
how does activation energy affect a chemical reaction?
oa it increases the energy of the reactants.
ob. it determines how difficult it is to start the reaction.
oc it determines how much product can form.
od. it decreases the energy of the products.

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
