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.
