Question: In a reaction at equilibrium, what is the effect of increasing the pressure if the number of moles of gas is equal on both sides?

Options:

Correct Answer: No effect on equilibrium

Solution:

If the number of moles of gas is equal on both sides, increasing the pressure has no effect on the equilibrium position.

In a reaction at equilibrium, what is the effect of increasing the pressure if the number of moles of gas is equal on both sides?

Step 1: Understand what equilibrium means. It is a state where the forward and reverse reactions occur at the same rate.
Step 2: Identify the reaction and the number of moles of gas on both sides. For example, if you have 2 moles of gas on the reactant side and 2 moles on the product side, they are equal.
Step 3: Know that pressure affects gases. Increasing pressure usually shifts the equilibrium towards the side with fewer moles of gas.
Step 4: Since the number of moles of gas is equal on both sides, increasing the pressure does not favor one side over the other.
Step 5: Conclude that if the number of moles is equal, increasing the pressure has no effect on the position of equilibrium.

Le Chatelier's Principle – This principle states that if a system at equilibrium is subjected to a change in pressure, temperature, or concentration, the system will adjust to counteract that change and restore a new equilibrium.
Equilibrium Position – The position of equilibrium refers to the concentrations of reactants and products in a reversible reaction at equilibrium.
