Question

The enthalpy change for the reaction
C(𝑔) +$\frac{1}{2}$ O2(𝑔)→CO(𝑔) is _______ kJ per mole of CO(𝑔) produced.
(rounded off to one decimal place)
[Given:
C(𝑔)+O2(𝑔) → CO2(𝑔), ΔHrxn = −393.5 kJ per mole of CO2(𝑔) produced
CO2(𝑔) → CO(𝑔) +$\frac{1}{2}$ O2(𝑔), ΔHrxn = 283.0 kJ per mole of CO(𝑔) produced]

Answer 1

The correct answer is: -111
