Question

In the reaction $2 \mathrm{~A}+\mathrm{B} \rightarrow \mathrm{A}_2 \mathrm{~B}$, if the concentration of A is doubled and that of B is halved, then the rate of the reaction will

Professor PC Thomas Classes · Answer

Assuming elementary reaction, Rate $= k[A]^2[B]$. New Rate $= k(2A)^2(B/2) = 2 	imes$ Rate. Increases 2 times.
