Question
The standard heat of formation of carbon atom in gaseous state in kJ/mol is -
áƒHo (atomisation of CO gas) = 1072 kJ/mol
áƒHo (formation of ′O′ gas) = 247 kJ/mol
áƒHo (formation of CO gas) = -114 kJ/mol
Options
A.400
B.311
C.600
D.711
Solution
CO(g) → C (g) + O (g).
1072 = áƒfHo(C,g) + 247 - (-144)
áƒfHo (C,g) = 711
1072 = áƒfHo(C,g) + 247 - (-144)
áƒfHo (C,g) = 711
