Rate law

2012 AIPMT-PRE 1 question

1. 1 Chemical Kinetics
   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:
   A Rate = $k[A]^2[B]$ B Rate = $k[A][B]^2$ C Rate = $k[A]^2[B]^2$ D Rate = $k[A][B]$
