The following equation represents the decomposition of a generic diatomic element in its standard state.

1/2 X_{2}(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}
