4.9     A reaction is first order in A and second order in B.

           (iii) How is the rate affected when the concentrations of both A and B are doubled?

M manish

If the concentration of [A] and[B] is increased by 2 times, then

-\frac{d[R]}{dt}=k[2A][2B]^{2}

               =8k[A][B]^{2}

Therefore, the rate of reaction will increase 8 times.
