| I. Ostwalds theory and Maxwells theory related to chemical kinetics. |
| II. For a first order reaction, \[{{t}_{1/2}}=\frac{0.693}{k}\] |
| III. Molecularity of a reaction may be fraction. |
| IV. Rate of zero order is independent of initial concentration. |
A) I and II
B) I and III
C) III and IV
D) I, II and IV
E) All of these
Correct Answer: D
Solution :
III is incorrect because molecularity of reaction can never be fraction Maxwells theory is related to gases and Ostwalds theory to dilute solutions and relate the degree of ionization with concentration.
