The enthalpy of formation of CO2 (g) is -394 kJ mol-1. Consider the following four reactions. (Given AH T mb (C, H6, I) = -3268 kJ 1 i. C, He (1) + 1.25 O (9) → CO2 (9) + ii. Cigraphite) + Ozt6) CO) iii. Cigraphite) + 20) → CO29) iv. Cgrophite) + O20) → CO2() In which of these reactions will 394 kJ of heat be evolved? The enthalpy of formation of CO2 (g) is -394 kJ mol-1.
