The test covers content from both year 12 and 13 OCR on chemical equilibrium. A markscheme with model answers is also included which enables students self assess their answers in class with their teacher or as a homework task. The test is based on the following learning objectives: Apply le Chatelier’s principle to deduce qualitatively (from appropriate information) the effect of a change in temperature, concentration or pressure, on a homogeneous system in equilibrium. Explain that a catalyst increases the rate of both forward and reverse reactions in an equilibrium by the same amount resulting in an unchanged position of equilibrium Deduce, for homogeneous and heterogeneous reactions, expressions for the equilibrium constant Kc. Calculate the values of the equilibrium constant, Kc (from provided or calculated equilibrium moles or concentrations), including determination of units. Estimate the position of equilibrium from the magnitude of Kc. Calculate, given appropriate data, the concentration or quantities present at equilibrium. Deduce, for homogeneous and heterogeneous reactions, expressions for the equilibrium constant Kp. Calculate the values of the equilibrium constant, Kp (from provided or calculated equilibrium moles or pressures), including determination of units. Explain the effect of changing temperature on the value of Kc or Kp for exothermic and endothermic reactions. State that the value of Kc or Kp is unaffected by changes in concentration or pressure or by the presence of a catalyst. Explain how Kc or Kp controls the position of equilibrium on changing concentration, pressure and temperature Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons including using your own lesson PowerPoints is a fundamental skill of a qualified/unqualified teacher that will be reviewed during these scenarios outlined above
