Consider the following statements.
i) Increase in concentration of rectant increases the rate of a zero order reaction.
ii) rate constant k is equal to collision frequency a if `E_(a)=0`
iii) rate constant k is equal to collision frequency A if `E_(a) = infty`.
iv) In k vs T is a straight line.
v) In k vs `1//T` is a straight line.
Correct statements are:

Options

A. (i) and (iv)
B. (ii) and (v)
C. (iii) and (iv)
D. (ii) and (iii)

Answer

B

Explanation

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.
