Assertion(A): Five times increase in pressure on reaction.
 \(N_2 (g) + 3H_2(g) \rightleftharpoons 2NH_3 (g) \)
at equilibrium doesn't change Kp.
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 and R is false.
4. A and R both are false.
