QUESTION 11
Use the standard reaction enthalpies given below to determine AH°rxn for the following reaction:
4 NO(g) + 2 O2(g) → 4 NO2(g)
AH°rxn
N2(g) + O2(g) → 2 NO(g)
1/2 N2(g) + O2(g) → NO2(g)
AH°rxn = +183 kJ
AH°
= +33 kJ
QUESTION 12
Use the standard reaction enthalpies given below to determine AH°rxn for the following reaction:
P4(g) + 10 Cl₂(g) → 4 PC15(s)
ΔΗ
rxn = ?
AH°rxn
PC15(s)→ PC13(g) + Cl2(g)
P4(g) + 6 Cl2(g) → 4 PC13(9)
AH°rxn = +157 kJ
AH°rxn
ΔΗ
= -1207 kJ
