APFIVE Calculating Enthalpy With Hesss Law
Given the following chemical reactions and their corresponding enthalpy changes:
C(s) + O₂(g) → CO₂(g) ΔH = -393.5 kJ/mol
CO(g) + ½O₂(g) → CO₂(g) ΔH = -283.0 kJ/mol
Based on these data, what is the enthalpy of formation for CO(g) in kJ/mol?
A
-221.0 kJ/mol
B
-110.5 kJ/mol
C
+110.5 kJ/mol
D
-676.5 kJ/mol
