Chemical Equilibria topic check · H1 Chemistry 8873
Check what you know about H1 Chemistry Chemical Equilibria, practise what needs work, then check your progress and come back for a later review.
Learning objectives
- explain, in terms of rates of the forward and reverse reactions, what is meant by a reversible reaction and dynamic equilibrium
- state Le Chatelier’s Principle and apply it to deduce qualitatively (from appropriate information) the effects of changes in concentration, pressure or temperature, on a system at equilibrium
- deduce whether changes in concentration, pressure or temperature or the presence of a catalyst affect the value of the equilibrium constant for a reaction
- deduce expressions for equilibrium constants in terms of concentrations, Kc
- calculate the values of equilibrium constants in terms of concentrations from appropriate data
- calculate the quantities present at equilibrium, given appropriate data (such calculations will not require the solving of quadratic equations)
- describe and explain the conditions used in the Haber process, as an example of the importance of an understanding of chemical equilibrium in the chemical industry
