The relevant thermodynamic data, under standard conditions, for the reaction H2(g) + ½O2(g) → H2O(g) are summarised below:
∆hf ° kJ mol−1: −241.81
∆gf ° kJ mol−1: −228.59
(a) Compute the equilibrium constant K of this reaction at T = 298 K.
(b) Compute the corresponding K at 500 K. To simplify your calculations for this temperature, it is suggested you make the appropriate simplifying assumption. State the assumption you have made.
