2 A(g) <--> A2 (g)
Qp = [p(A2)]/[p(A)]2
38)
Initial state 1 has more percentage of A(g) molecules (monoatomic) than equilibrium state.
Since the partial pressure of A(g) is higher in initial state 1 than equilibrium state, the reaction will shift forward.
A) Qp < Kp
39)
Initial state 2 has less percentage of A(g) molecules (monoatomic) than equilibrium state.
Since the partial pressure of A(g) is lower in initial state 2 than equilibrium state, the reaction will shift backward.
D) Qp > Kp
