Copper metal can be obtained by heating copper oxide in the presence of carbon monoxide, CO, according to the reaction:
CuO(s) + CO(g) --> Cu(s) + CO2(g)

Calculate Delta H° in kJ using the following thermochemical equations.

2CO(g) + O2(g) --> 2CO2(g) DeltaH° -566.1
2Cu(s) + O2(g) --> 2CuO(s) DeltaH° -310.5

  • Chemistry -

    Take 1/2 equation 2.
    Take 1/2 equation 2 and reverse it (and delta H).
    Add the two.
