Gases A, B and C react reversibly in a sealed vessel.
A(g)⇌B(g)+C(g) \mathrm{A(g) \rightleftharpoons B(g) + C(g)} A(g)⇌B(g)+C(g)A solid absorbent is held in a separate compartment inside the vessel. It absorbs C but does not absorb A or B.
The gas mixture is allowed to reach equilibrium. The compartment is then opened until some C has been absorbed. The compartment is closed again before the gas mixture reaches a new equilibrium.
Predict how the amount of B in the gas mixture changes as a new equilibrium is established. Explain your answer.
