On increasing the pressure, the direction in which the gas phase reaction proceeds to re-establish equilibrium is predicted by applying Le-Chatelier's principle. Consider the reaction,
Which of the following is correct, if the total pressure at which the equilibrium is established is increased without changing the temperature?
| 1. | K will remain the same. |
| 2. | K will decrease. |
| 3. | K will increase. |
| 4. | K will increase initially and then decrease, when pressure is very high. |
Hint: K is only temperature dependent.
Explanation:
In the reaction,
If the total pressure at which the equilibrium is established, is increased without changing the temperature, K will remain same. K changes only with change in temperature.
