Chemistry
Use data in Appendix C in the textbook to calculate ΔH∘ in(kJ/mol) , ΔS∘ in (j/mol-K) , and ΔG∘ in (kJ/mol) at 25 ∘C for eachof the following reactions: 2P(g)+10HF(g)→2PF5(g)+5H2(g)
Appendix C:
P(g): dH:316.4; dG: 280.0; S:163.2
HF(g): dH: -268.61; dG: -270.70; S:173.51
PF5(g): dH:-1594.4; dG: -1520.7; S: 300.8
H2(g): dH:217.94; dG: 203.26; S: 114.60
