Solution :(A)`2.303"log"_10 K_2/K_1=E_a/R[(T_2-T_1)/(T_2T_1)]IMPLIES K_2/K_1=11`
`T_2=298 K,T_1=273 K, E_a=65000 J, R=8.314` J/(mol K)
(B)`2.5/20=1/8=(1/2)^nimplies n=3implies t=3xx0.693/0.0693=30`
( C )Zero order :`t_(1//2)=a/(2K) " " I order : t_(1//2)=0.693/K`
`1/(2K_1)=0.693/K_2 implies K_2/K_1=2xx0.693`
(D)`t_(1//2)prop(a)^(1-n)` or `(1-n)=(logt'_(1//2)-logt''_(1//2))/(loga'-loga'')`
`t_(1//2)prop1/a^(n-1)implies 480/240=(0.0677/0.136)^(n-1)" " n=0`
