In a reaction. A + B → product, rate is doubled when the concentration of B is doubled, and rate increases by a factor of 8 when the concentration of both the reactants (A and B) are doubled rate law for the reaction can be written as
(a) rate = k[A][B]2
(b) rate = k[A]2[B]2
(c) rate = k[A][B]
(d) rate = k[A]2[B]
