| Assertion (A): | For the reaction: H2(g) + I2(g) \(\rightleftharpoons\) 2HI(g), if the volume of the vessel is reduced to half of its original volume, the equilibrium concentration of all gases will be doubled. |
| Reason (R): | According to Le-Chatelier's principle, reaction shifts in a direction that tends to minimize the effect of stress. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
