Question: For the equilibrium reaction 2NO2(g) ⇌ N2O4(g), what is the effect of increasing the temperature?

Options:

Correct Answer: Shifts equilibrium to the left

Solution:

If the reaction is exothermic, increasing the temperature will shift the equilibrium to the left, favoring the formation of reactants (NO2).

For the equilibrium reaction 2NO2(g) ⇌ N2O4(g), what is the effect of increasing the temperature?

For the equilibrium reaction 2NO2(g) ⇌ N2O4(g), what is the effect of increasing the temperature?

Step 1: Identify the reaction type. The reaction is 2NO2(g) ⇌ N2O4(g).
Step 2: Determine if the reaction is exothermic or endothermic. If it releases heat, it is exothermic.
Step 3: Understand Le Chatelier's Principle, which states that if a system at equilibrium is disturbed, it will shift to counteract the disturbance.
Step 4: If the reaction is exothermic, increasing the temperature adds heat to the system.
Step 5: According to Le Chatelier's Principle, the system will shift to the left to absorb the added heat, favoring the formation of reactants (NO2).

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.
