Effect of Temperature on Reversible Reactions

Flashcards created to help review the effects of temperature on reversible reactions at equilibrium, based on the lecture content.

What does Le Chatelier's principle state about equilibrium systems when conditions change?

The system responds to counteract the change.

In a reversible reaction, if the forward reaction is exothermic, what is true about the reverse reaction?

The reverse reaction is endothermic.

What happens to the equilibrium position when the temperature increases in an exothermic forward reaction?

The equilibrium shifts to the left to reduce the temperature.

When the temperature in an exothermic reaction decreases, which direction does the equilibrium shift?

The equilibrium shifts to the right to increase the temperature.

What is the effect on the concentration of NO2 when the temperature of an exothermic reaction is increased?

The amount of NO2 increases.

What is the effect on the concentration of N2O4 when the temperature of an exothermic reaction is decreased?

The amount of N2O4 increases.

Why might students find the concept of temperature effects on reversible reactions tricky?

The complexity of how systems at equilibrium respond to temperature changes can be challenging to understand.
