question 18

Multiple Choice

Choose the correct equation for the standard enthalpy of formation of CO(g) ,where $\Delta$ H_f° for CO = -110.5 kJ/mol (gr indicates graphite) .

• A)2C(gr)+ O₂(g)\(\to\) 2CO(g),\(\Delta\)H° = -110.5 kJ
• B)C(gr)+ O(g)\(\to\) CO(g),\(\Delta\)H° = -110.5 kJ
• C)C(gr)+ O₂(g)\(\to\) CO(g),\(\Delta\)H° = -110.5 kJ
• D)C(gr)+ CO₂(g)\(\to\) 2CO(g),\(\Delta\)H° = -110.5 kJ
• E)CO(g)\(\to\) C(gr)+ O(g),\(\Delta\)H° = -110.5 kJ
