Final answer:
The number of carbon dioxide molecules on each side of the membrane after equilibrium depends on the specific reaction context.
Step-by-step explanation:
After equilibrium, the number of carbon dioxide molecules on each side of the membrane depends on the specific context of the question and the reaction being referred to. The information provided in the question does not specify the reaction in which equilibrium is reached, so it is not possible to determine the exact number of carbon dioxide molecules on each side of the membrane.
