For a reaction between A and B the order with respect to A is 2 and the other with respect to B is 3 . The concentrations of both A and B are doubled, the rate will increase by a factor of:

Options

  1. A12
  2. B16
  3. C32
  4. D10

Correct answer

C. 32

Step-by-step solution

aligned & Rate ₁=k[ ~A ]^2[ ~B ]^3 & Rate ₂=k[2 ~A ]^2[2 ~B ]^3 & Rate ₂=32[ Rate ]₁ & aligned
