9. Show that for a first order reaction, the time required for half the change isindependent of initial concentration.
 
10. A reaction is first order in A and second order inB.
a) Write differential rateequation.
b) How is the rate affected when the concentration of A istripled?
c) How is the rate affected when the concentration of both A and B aredoubled?
 
11.An artifact containing wood has only 80% of the C14 activity found in a livingtree. Estimate the age of the artifact if t1/2of C14 is 5730years.
 
12. The time required for 10% completion of a first order reaction at 298 K is equal tothat required for its 25% completion at 308K.if the value of A is 4 x 10 10 /s, calculate kat 318K andEa
 
13. (a) For a reaction A + B → P, the rate is givenby
 
Rate = k[A]2[B]
(i) How is the rate of reaction affected if the concentration of A isdoubled?
(ii) What is the overall order of reaction if B is present in largeexcess?
(b) A first order reaction takes 23.1 minutes for 50% completion. Calculate thetime required for 75% completion of thisreaction.
(Given : log 2 = 0.301, log 3 = 0.4771, log 4 =0.6021)
