Question

What effect does increasing the pressure have on this equilibrium? Hint: which reaction produces fewer gas molecules?

A. The forward reaction is favored.


B. Pressure has no effect on gaseous systems.


C. The reverse reaction is favored.

Answer 1

You have not provided the required equation however, a question on equilibrium of gases has to do with Le Chatelier's principle and I'll point you to the answer.

Step-by-step explanation:

Le Chatelier's principle is used to determine the interaction of a system,m a system can be affected by changes in temperature, pressure or gas concentration.

If the pressure of a system in equilibrium is increased, this will cause a shift in the system in order to offset the change and adjust equilibrium.

With an increasing pressure, the equilibrium will shift to the side of the reaction having lesser moles of gas, it could be the forward or backward reaction.

Answer 2

A. The forward reaction is favored.

Explanation: According to Le Chatelier's principle, "When there is an increase in pressure for a system at equilibrium (gases), the reaction which involves a reduction in pressure ( reaction which produced fewer gas molecules) will be favored."
