(a) A reaction is second order in A and first order in B .
(I Write the differential rate equation.
(ii) How is the rate afected on increasing the concentration of A three times?
(iii) How is the rate affected when the concentration of both A and B doubled?
(b) A first order reaction takes 40 minutes for 30% decomposition. Calculate t_(1//2)` for this reaction. (Given log 1.428 = 0.1548)
