When heated to a high temperature, coke (mainly carbon, obtained by heating coal in the absence of air) and steam produce a mixture called water gas, which can be used as a fuel or as a starting place for other reactions. The equation for the production of water gas is

(a) Use standard enthalpies of formation to determine the enthalpy change for this reaction.

(b) Is the reaction exo- or endothermic?

(c) What is the enthalpy change if 1000.0 kg (1 metric ton) of carbon is converted to water gas?
