The following reaction is initiated and the concentrations are measured after ten minutes:
A(g) + 3 B(g) AB3(g) Kc = 1.33 × 10−2
[A] = 1.78 M [B] = 2.21 M [AB3] = 1.19 M
Is the reaction in equilibrium?
a. Yes.
b. No, because Q < K.
c. No, and the [AB3] must increase to establish equilibrium.
d. No, because Q > K.
e. There is no way to tell.
Answer: d. No, because Q > K.
