Consider the following statements
(i) increase in the concentration of reactants increase the rate of zero order reactions
(ii) rate constant, k is equal to collision frequency of A if `E_(a)=0`
(iii) rate constant, `k` is equal to the collision frequency if `E_(a) = infty`
(iv) `l n k vs T` is straight line
(v) `l n k vs 1//T` is a straight line
correct statements are

Options

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

Answer

B

Explanation

Rate of zero order is independent of concentration
`:.` (i) is wrong
when `E_(a) = 0,k=A`
when `E_(a) = prop K ne A`
Plot of ` l n k vs 1//T` is a straight line
Hence (ii) and (v) are correct.
