Question: In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what will happen if H2 is removed from the system at equilibrium?

Options:

Correct Answer: Equilibrium shifts to the left

Solution:

Removing H2 will shift the equilibrium to the left to produce more H2, thus favoring the reactants.

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what will happen if H2 is removed from the system at equilibrium?

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what will happen if H2 is removed from the system at equilibrium?

Step 1: Understand that the reaction CO(g) + 2H2(g) ⇌ CH3OH(g) is at equilibrium, meaning the forward and reverse reactions are happening at the same rate.
Step 2: Recognize that H2 is one of the reactants in this reaction.
Step 3: When H2 is removed from the system, there is less H2 available for the reaction.
Step 4: According to Le Chatelier's principle, if a reactant is removed, the equilibrium will shift to try to replace that reactant.
Step 5: In this case, the equilibrium will shift to the left, which means it will favor the formation of the reactants (CO and H2) to produce more H2.
Step 6: Therefore, the overall effect of removing H2 is that it will increase the concentration of the reactants.

Le Chatelier's Principle – This principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change.
Equilibrium Shift – Understanding how the removal of a reactant affects the direction of the equilibrium shift.
