I need to calculate the enthalpy change of the POCL3.

  • Chemistry -

    From what to what?

  • Chemistry -

    Well the question state that:

    Using the molar bond enthalpies given in table 2, calculate the overall enthalpy change for reaction POCL3.

    Table 2:
    P-CL 326
    O=O 498
    P=O 544

    Thanks for your help. By Lowrence.

    This looks very much like the S104 TMA04 question?
