Question: In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what is the effect of increasing the concentration of CO? (2023)

Options:

Correct Answer: Shift to the right

Exam Year: 2023

Solution:

Increasing the concentration of CO will shift the equilibrium to the right, favoring the formation of CH3OH.

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what is the effect of increasing the concentration of CO? (2023)

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), what is the effect of increasing the concentration of CO? (2023)

Step 1: Identify the reaction: CO(g) + 2H2(g) ⇌ CH3OH(g).
Step 2: Understand what 'increasing the concentration of CO' means: It means adding more CO to the reaction mixture.
Step 3: Recall Le Chatelier's Principle: This principle states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Apply Le Chatelier's Principle: By increasing the concentration of CO, the system will try to reduce the amount of CO by using it up in the reaction.
Step 5: Determine the direction of the shift: The reaction will shift to the right to produce more CH3OH.
Step 6: Conclude: Therefore, increasing the concentration of CO will favor the formation of CH3OH.
