• # question_answer For reaction $2A+B\to$ products, the active mass of B is kept constant and that of A is doubled. The rate of reaction will then                                               [MP PET 1993] A)                 Increase 2 times               B)                 Increase 4 times C)                 Decrease 2 times             D)                 Decrease 4 times

Rate = $K{{(A)}^{2}}{{(B)}^{1}}$ on doubling the active mass of A the rate of reaction increase 4 times.
