The following equation represents the decomposition of a generic diatomic element in its standard state.
1/2 X2(g) → X(g)
Assume that the standard molar Gibbs energy of formation of X(g) is 4.76 kJ•mol-1 at 2000. K and - 65.63 kJ•mol-1 at 3000. K. Determine the value of K (the thermodynamic equilibrium constant) at each temperature.
K at 2000. K = _____
K at 3000. K = _____
Assuming that delta H°rxn, is independent of temperature, determine the value of Δ H°rxn from these data.
ΔH°rxn = ______ kJ mol-1
