Chemical equilibria written questions
Explain equilibrium changes and solve H1 Chemistry equilibrium problems through written practice with marking guidance.
Learning goals
- Explain reversible reactions and dynamic equilibrium in terms of forward and reverse reaction rates
- State Le Chatelier's Principle and use it to predict how concentration, pressure or temperature changes affect a system at equilibrium
- Deduce whether concentration, pressure, temperature or a catalyst changes the value of an equilibrium constant
- Deduce the expression for the equilibrium constant Kc
- Calculate Kc from equilibrium data
- Calculate the amounts present at equilibrium from given data
- Describe and explain the conditions of the Haber process as an example of equilibrium in industry
