be able to deduce an expression for K_p, for homogeneous and heterogeneous systems, in terms of equilibrium partial pressures in atm

be able to calculate a value, with units where appropriate, for the equilibrium constant (K_c and K_p) for homogeneous and heterogeneous reactions, from experimental data

know the effect of changing temperature on the equilibrium constant (K_c and K_p), for both exothermic and endothermic reactions

understand that the effect of temperature on the position of equilibrium is explained using a change in the value of the equilibrium constant

understand that the value of the equilibrium constant is not affected bychanges in concentration or pressure or by the addition of a catalyst
