Topic Summary: Dynamic Equilibrium & Le Chatelier's Principle

Summary

Sample Flashcards

What is dynamic equilibrium?

When rate of forward reaction = rate of backward reaction in a closed system

State Le Chatelier's Principle

If a system at equilibrium is disturbed, it will shift to counteract/oppose the change

Sample Questions

At dynamic equilibrium, which of the following is true?

A. The rate of the forward reaction equals the rate of the reverse reaction
B. The concentrations of reactants and products are always equal
C. The forward reaction stops and only the reverse reaction continues
D. All chemical reactions have stopped

1 markfoundation

Explain the effect of increasing temperature on the position of an equilibrium where the forward reaction is exothermic.
