    Solutions

     

  • Question 8/10
    4 / -1

    The standard heat of combustion of carbon(s), sulphur(s) and carbon disulphide(l) are – 390, – 290 and – 1100 kJ/mol respectively. The standard heat of formation of carbon disulphide (l) is -

    Solutions

    C(s) + 2S(s) → CS2(l)

    ΔfH° = -390 - (290) × 2 - (-1100)

    = + 130 kJ mol-1
