A hypothetical reaction has a rate law of:
Rate = k [A]²[B]
Which statement about this reaction is most probably correct?
a. Doubling the concentration of A will double the rate of the reaction.
b. Tripling [A] will affect the rate twice as much as tripling [B].
c. The reaction mechanism involves the formation of B_2 at some stage.
d. The reaction mechanism involves more than one step.
