  • Q:

    Using the information in the table below, calculate the enthalpy change for the reaction:

    CS2 + 3 O2 → CO2 + 2 SO2
    Reaction Heat of Formation (kJ/mol)
    C + O2 → CO2 -400
    S + O2 → SO2 -250
    C + 2 S → CS2 90


     

    A

    -560 kJ/mol

    B

    -810 kJ/mol

    C

    -740 kJ/mol

    D

    -990 kJ/mol
