# Solution: Calculate ΔHrxn for the following reaction: 5 C(s) + 6 H2(g) → C5H12(l)Use the following reactions and given ΔH's.C5H12(l) + 8 O2(g) → 5 CO2(g) + 6 H2O(g), ΔH = –3244.8 kJC(s) + O2(g) → CO2(g), ΔH = –393.5 kJ2 H2(g) + O2(g) → 2 H2O(g), ΔH = –483.5 kJ

###### Problem

Calculate ΔHrxn for the following reaction: 5 C(s) + 6 H2(g) → C5H12(l)
Use the following reactions and given ΔH's.
C5H12(l) + 8 O2(g) → 5 CO2(g) + 6 H2O(g), ΔH = –3244.8 kJ
C(s) + O2(g) → CO2(g), ΔH = –393.5 kJ
2 H2(g) + O2(g) → 2 H2O(g), ΔH = –483.5 kJ
