1.	(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 are 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)
Answer» Solution :(i) `-(DA)/(DT)=k[A]^(2)[B]" (ii) RATE increases 8 times (iii) 77.87 min"`
