Choose the Correct Equation for the Standard Enthalpy of Formation

question 34

Multiple Choice

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

• A) C_graphite(s) + CO₂(g)  2CO(g),  H° = -110.5 kJ
• B) C_graphite(s) + O(g)  CO(g),  H° = -110.5 kJ
• C) 2C_graphite(s) + O₂(g)  2CO(g),  H° = -110.5 kJ
• D) ,  H° = -110.5 kJ
• E) CO(g)  C_graphite(s) + O(g),  H° = -110.5 kJ
