Question

Give handwritten answer of the question-

wish to know the enthalpy change for the formation of quid PC, trom the elements
Pals) +6 Cla(e) 4 PCh() A, H -7
The enthaipy change for the formation of PC, from the elements can be determined experimentally, as can the enthalpy change for the reection of PC, () with
more chiorine to give PC (0):
Pala) + 10 Ch(e) -4 PCL(0)
AN --1774.0 kJ/mol - rn
PCL(0 + Clie) - PCL (s)
AH--123 J/mel- n
Use these data to calculate the enthalpy change for the formation of 2.30 mal of PC,() from phosphorus and chiorine.
