| I. Chemical equilibrium can be attained only from one side. |
| II. Chemical equilibrium will continue indefinitely if the conditions such as temperature and concentration are not changed. |
| III. Chemical equilibrium is dynamic in nature. |
| IV. Chemical equilibrium can be attained faster by use of a catalyst. |
A) I and II
B) II, III and IV
C) l, III and IV
D) All of these
Correct Answer: B
Solution :
(i) Chemical equilibrium can be attained from either side. (ii) Chemical equilibrium will continue indefinitely .if the conditions such as temperature and concentration not changed. (iii) It is dynamic in nature. (iv) Chemical equilibrium can be attained in a lesser time by the use of a catalyst but catalyst does not change the chemical equilibrium as it affects the rate of both forward and backward to the same extent.
