Homework Help: Chemistry

Posted by Samantha on Tuesday, March 3, 2009 at 1:05pm.

How would you calculate delta H for the following reaction:
2P + 5Cl2 -> 2PCl5

Given:
PCl3 + Cl2 -> PCl5 Delta H=-87.9 kJ
2P + 3Cl2 -> 2PCl3 Delta H=-574 kJ

I have no clue how to do this since I was absent. Can someone help?
