Choose the Correct Equation for the Standard Enthalpy of Formation

Question 80

Multiple Choice

Choose the correct equation for the standard enthalpy of formation of CO(g) , where ΔH°f for CO = -110.5 kJ/mol.


A) Cgraphite(s) + CO2(g) → 2CO(g) , ΔH° = -110.5 kJ
B) Cgraphite(s) + O(g) → CO(g) , ΔH° = -110.5 kJ
C) 2Cgraphite(s) + O2(g) → 2CO(g) , ΔH° = -110.5 kJ
D) Choose the correct equation for the standard enthalpy of formation of CO(g) , where ΔH°<sub>f</sub> for CO = -110.5 kJ/mol. A) C<sub>graphite</sub>(s) + CO<sub>2</sub>(g) → 2CO(g) , ΔH° = -110.5 kJ B) C<sub>graphite</sub>(s) + O(g) → CO(g) , ΔH° = -110.5 kJ C) 2C<sub>graphite</sub>(s) + O<sub>2</sub>(g) → 2CO(g) , ΔH° = -110.5 kJ D) , ΔH° = -110.5 kJ E) CO(g) → C<sub>graphite</sub>(s) + O(g) , ΔH° = -110.5 kJ , ΔH° = -110.5 kJ
