For a reaction between A and B the order with respect to A is 2 and the order with respect to B is 3. The concentrations of both A and B are doubled, the rate will increase by a factor of: (NEET Kar. 2013)
A.10
B.12
C.16
D.32✓ Correct
Explanation
Rate1 = k[A]2[B]3 when concentrations of both A and B are doubled then Rate2 = k[2A]2[2B]3 = 32 k[A]2[B]2 rate will increase by a factor of 32.
