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 concentrations of both the reactants (A and B) are doubled. Rate law for the reaction can be written as: (AIPMT 2012)
A.Rate = k[A][B]2 (b) Rate = k[A]2[B]2
C.Rate = k[A][B] (d) Rate = k[A]2[B]
Explanation
According to statement given in the question, it is clear that 2 r A and r B That means order of reaction with respect to B is 1 and w.r.t A is 2 Hence, Rate = k[A]2[B]1
