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

Options:

Correct Answer: Shifts equilibrium to the right

Solution:

If the reaction is exothermic, decreasing the temperature will shift the equilibrium to the right to produce more products (CH3OH).

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

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

Step 1: Identify the reaction: CO(g) + 2H2(g) ⇌ CH3OH(g).
Step 2: Determine if the reaction is exothermic or endothermic. (Exothermic means it releases heat, endothermic means it absorbs heat.)
Step 3: If the reaction is exothermic, understand that heat can be considered a product of the reaction.
Step 4: When the temperature is decreased, it is like removing heat from the system.
Step 5: According to Le Chatelier's principle, the system will try to counteract this change by producing more heat.
Step 6: To produce more heat, the equilibrium will shift to the right, favoring the formation of more products (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 vs. Endothermic Reactions – Understanding whether a reaction releases heat (exothermic) or absorbs heat (endothermic) is crucial for predicting the effect of temperature changes on equilibrium.
