Question

Consider the reaction 2A(g) □ A2(g) The following pictures equilibrium state of the system. represent two possible initial states and the Initial state 1 Initial state2 Equilibrium state 38) For initial state 1 what is the relationship between the reaction quotient, Qp. and the equilibrium constant, PLEASE ExPIAIN, WILL KATE AND conament 39) For initial state 2 what is the relationship between the reaction quotient, Qpi and the equilibrium constant, 40) What are the signs (+ or-) of All, AS, and Δ@when the system spontaneously goes from initial state 2 to

Answer 1

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
