(a) For a reaction A+B to P, the rate is given by Rate =k[A][B]^(2) (i) How is the rate of reaction affected if the concentration of B is doubled ? (ii) What is the overall order of reaction if A is present in large excess ? (b) A first order reaction takes 30 minutes for 50% completion. Calculate the time required for 90%. Completion of this reaction (log2=0.310).

SOLUTION :(a) (i) 4 times (ii) 2 (b) `k=(0.693)/(30)MIN^(-1),t_(90%)=(2.303)/(k)log""(100)/(100-90)=99.69" min"`
