Question

In the reaction to be given this product if the concentration of b is doubled the rate of reaction will increase by

Answer 1

$ASSALAMUALAIKUM$

As the rate of the reaction becOmes two timees on doubling the concentartion of b so the reaction is first ordr wrt to b when both a and b is doubled then rate becomes eight times.as rxn is 1order art to b due to rate increases two times hence due to A rate increases four times which is 2^2 hence reaction is second order wrt to a

Rate law=(a^2)(b^1)
