  • Calculate stardard reaction using Hess law?

    calculate the standard reaction enthalpy for the combustion of one mole of methane gas into carbon monoxide (CO gas) and 2 H20(g)

    CH4(g) + 3/2 O2(g) -------> CO(g) + 2 H20(g)

    From the following data:

    a. CH4(g) + 2 O2(g) -------> CO2(g) + 2 H2O(g) H*= -802kJ

    b. CH4(g) + CO2(g) -------> 2 CO(g) + 2 H2(g) H*= +206kJ

    c. CH4(g) + H20(g) -------> CO(g) + 3 H2(g) H*= +247kJ
