Question

For the reaction $A + B \rightarrow \text{Products}$, it is found that the order with respect to $A$ is $2$ and the order with respect to $B$ is $3$ in the experimental rate expression. When the concentrations of both $A$ and $B$ are doubled, the rate will increase by a factor of what integer?

Answer: 32

💡 Solution & Explanation

$\text{Rate}_{initial} = k[A]^2[B]^3$. When both are doubled, $\text{Rate}_{new} = k(2[A])^2(2[B])^3 = k \cdot 4[A]^2 \cdot 8[B]^3 = 32 \times k[A]^2[B]^3$. The rate increases by a factor of 32.
