For a reaction between AA and BB the order with respect to AA is 2 and the other with respect to BB is 3 . The concentrations of both A\mathrm{A} and B\mathrm{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

 Rate 1=k[ A]2[ B]3Rate⁡2=k[2 A]2[2 B]3∴ Rate 2=32[ Rate ]1\begin{aligned}& \text{ Rate }_1=k[\mathrm{~A}]^2[\mathrm{~B}]^3 \\ & \operatorname{Rate}_2=k[2 \mathrm{~A}]^2[2 \mathrm{~B}]^3 \\ & \therefore \quad \text{ Rate }_2=32[\text{ Rate }]_1 \\ & \end{aligned}
