Water gas, a mixture of h2 and co, is an important industrial fuel produced by the reaction of steam with red hot coke, essentially pure carbon.
c(s) + h2o(g) → co(g) + h2(g)
(a)
assuming that coke has the same enthalpy of formation as graphite, calculate δh⁰ (in kj) for this reaction.

(b)
methanol, a liquid fuel that could possibly replace gasoline, can be prepared from water gas and additional hydrogen at high temperature and pressure in the presence of a suitable catalyst.
2 h2(g) + co(g) → ch3oh(g)
under the conditions of the reaction, methanol forms as a gas. calculate δh⁰ (in kj) for this reaction.

calculate δh⁰ (in kj) for the condensation of gaseous methanol to liquid methanol.

(c)
calculate the heat transferred when 1.23 mol of liquid methanol combusts to form h2o(g) and co2(g).
