The industrial manufacture of hydrogen from methane is represented by the equation below. $\text{CH}_4(\text{g}) + \text{H}_2\text{O}(\text{g}) \rightleftharpoons \text{CO}(\text{g}) + 3\text{H}_2(\text{g}) \quad \Delta H^{\circ} = +205\,\text{kJ mol}^{-1}$ Under what conditions would hydrogen formation be favoured most?
