Q. No.
Consider the given two statements:
Assertion (A):
A five times increase in pressure at equilibrium doesn't change Kp for the following reaction 
\(N_2 (g) + 3H_2(g) \rightleftharpoons 2NH_3 (g) \)
Reason (R): Kp depends on the degree of dissociation, not on total pressure.
 
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.

2. Both assertion & reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is a true statement but the reason is false.
4. Both assertion and reason are false statements.
