A first order reaction takes 40 min for 30% decompositon.

(a) A reaction is second order in A and first order in B . (i) Write the differential rate equation. (ii) How is the rate affected 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)
