QUESTION 23
The enthalpy of reaction for the combustion of C to CO2 is -393.5 kJ/mol C, and the enthalpy for the combustion of CO to CO2 is -283.0 kJ/mol CO:
(i)
C(S) + 02(g) → CO2(g)
AH =-393.5 kJ
(ii)
Using these data, calculate the enthalpy for the combustion of C to CO:
(iii)
2C0(g) + 02g) → 2CO2(g) AH=-283.0 kJ
2C(s) + 02g)→ 2CO(g) AH=?
O A. -787.0 KJ
O B. -504.0 KJ
OC. 1070 KJ
O D. none of the above.
