1) the heat of combustion for the gases hydrogen, methane and ethane are β285.8, β890.4 and β1559.9 kj/mol respectively at 298k.
equation 1 h2 + 1β2o2 > h2o Ξ΄h = β285.8 kj
equation 2 ch4 + 2o2 > co2 + 2h2o Ξ΄h = β890.4 kj
equation 3 c2h6 + 7β2o2 > 2co2 + 3h2o Ξ΄h = β1559.9 kj
use the above equations to calculate (at the same temperature) the heat of reaction for the following reaction:
2ch4(g) > c2h6(g) + h2(g)
