| I. Increase in concentration of reactant 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
Correct Answer: B
Solution :
[b] According to Arrhenius equation, \[k=A{{e}^{-{{E}_{a}}/RT}}\] \[\therefore \] when \[{{E}_{a}}=0,k=A\] Also In k vs 1/T is a straight line with slope \[=-{{E}_{a}}/R.\] \[\therefore \] Statements (ii) and (v) are correct.
