Consider the following statements : (i) increase in concentration of reactant increases the rate of zero order reaction. (ii) rate constant k is equal to collision frequency A if E_(a)=oo. (iv) ln k vs T is a straight line. (v) ln k vs 1//T is a straight line. Correct statements are :

Answer»

(i) and (IV)
(ii) and (V)
(iii) and (iv)
(ii) and (iii)

Solution :RATE of zero order reaction is independent of concentration. Hence, (i) is wrong.
`K=Ae^(=-E_a//RT)`
When `E_a=0,` k = A, When `E_a=oo, k ne A `
Plot of In k vs 1/T is STRAIGHT line.
Hence, only (ii) and (v) are correcrt.
