Consider the following statements. i) ...

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:

A

i) and iv)

B

ii) and v)

C

iii) and iv)

D

ii) and iii)

Text Solution

Verified by Experts

The correct Answer is:
B

i) For zero order reaction the increases in concentration of reactants does not affect reaction rate.
ii) According to Arrhenius equation.
`k=Ae^(-Ea//RT)`
Where `E_(a) =0, k=A`
iii) When `E_(a) = infty, klt A`
iv) In k vs t is not a straight line
v) In k vs `1//T` is a straight line with slope `=(-Ea//R)`
Statements (ii) and (v) are `DeltaH` correct.
