Question: In a closed system at equilibrium, if the pressure is increased, what will happen to the equilibrium position?

Options:

Correct Answer: Shift to the side with fewer moles of gas

Solution:

Increasing the pressure will shift the equilibrium position to the side with fewer moles of gas.

In a closed system at equilibrium, if the pressure is increased, what will happen to the equilibrium position?

In a closed system at equilibrium, if the pressure is increased, what will happen to the equilibrium position?

Step 1: Understand that a closed system means no gas can enter or leave.
Step 2: Know that equilibrium is a state where the forward and reverse reactions happen at the same rate.
Step 3: Recognize that pressure is related to the number of gas molecules in a reaction.
Step 4: Remember that increasing pressure means there is less space for gas molecules.
Step 5: Identify that the system will try to reduce pressure by favoring the side of the reaction with fewer gas molecules.
Step 6: Conclude that increasing pressure shifts the equilibrium position to the side with fewer moles of gas.

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 state of a reversible reaction where the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.
Moles of Gas – In reactions involving gases, the number of moles on each side of the equilibrium can affect the position of equilibrium when pressure changes.
