The combination of coke and steam produces a mixture called coal gas, which can be used as a fuel or as a starting material for other reactions. if we assume coke can be represented by graphite, the equation for the production of coal gas is
2c(s)+2h2o(> ch4(g)+co2(g)
determine the standard enthalpy change for this reactionf rom the following standard enthalpies of reactions:
c(s)+h2o(> co(g)+h2(g) delta h=131.3 kj
co(g)+h2o(> co2(g)+h2(g) delta h=-41.2 kj
ch4(g)+h2o(> 3h2(g)+co(g) delta h=206.1 kj
