Question: In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), if the temperature is decreased, what will happen to the equilibrium?

Options:

Correct Answer: Shift to the right

Solution:

Decreasing the temperature for an exothermic reaction will shift the equilibrium to the right, favoring the formation of CH3OH.

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), if the temperature is decreased, what will happen to the equilibrium?

In the reaction CO(g) + 2H2(g) ⇌ CH3OH(g), if the temperature is decreased, what will happen to the equilibrium?

Step 1: Identify the reaction: CO(g) + 2H2(g) ⇌ CH3OH(g).
Step 2: Determine if the reaction is exothermic or endothermic. This reaction is exothermic because it releases heat when forming CH3OH.
Step 3: Understand Le Chatelier's Principle, which states that if a change is made to a system at equilibrium, the system will adjust to counteract that change.
Step 4: Recognize that decreasing the temperature is a change that affects the equilibrium.
Step 5: Since the reaction is exothermic, decreasing the temperature will shift the equilibrium to the right to produce more heat.
Step 6: Conclude that the equilibrium will shift to the right, favoring the formation of CH3OH.

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.
Exothermic Reactions – In exothermic reactions, heat is released, and decreasing temperature shifts the equilibrium towards the products.
