| Assertion: Equilibrium constant for the reverse reaction is the inverse of the equilibrium constant for the reaction in the forward direction. |
| Reason: Equilibrium constant depends upon the way in which the reaction is written. |
| Read the assertion and reason carefully to mark the correct option out of the options given below: |
A) If both assertion ad reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
[a] \[{{H}_{2}}_{(g)}+{{I}_{2}}_{(g)}\]⇌\[2H{{I}_{(g)}}\] \[{{K}_{C}}=\frac{{{\left[ HI \right]}^{2}}}{\left[ {{H}_{2}} \right]\left[ {{I}_{2}} \right]}\] For reverse reaction \[2H{{I}_{(g)}}\]⇌ \[{{H}_{2}}_{(g)}+{{I}_{2(g)}}\] \[{{K}_{C}}=\frac{\left[ {{H}_{2}} \right]\left[ {{I}_{2}} \right]}{{{\left[ HI \right]}^{2}}}=\frac{1}{{{K}_{C}}}\].
