The standard enthalpy of formation of \(\mathrm{CO}(g)\), \(\mathrm{CO}_2(g), \mathrm{N}_2 \mathrm{O}(g)\) and \(\mathrm{N}_2 \mathrm{O}_4(g)\) are respectively -10 , \(-393,81\) and \(-10 \mathrm{~kJ} \mathrm{~mol}^{-1}\). Enthalpy change (in \(\mathrm{kJ}\) ) of the following reaction is \[ \mathrm{N}_2 \mathrm{O}_4(\mathrm{~g})+3 \mathrm{CO}(\mathrm{g}) \longrightarrow \mathrm{N}_2 \mathrm{O}(\mathrm{g})+3 \mathrm{CO}_2(\mathrm{~g}) \]
- A -1058
- B 1058
- C -957
- D 957
Answer & Solution
Correct Answer
(A) -1058
Step-by-step Solution
Detailed explanation
Given, standard enthalpy of formation of \(\mathrm{CO}=-10 \mathrm{~kJ} / \mathrm{mol}\) Standard enthalpy of formation of \(\mathrm{CO}_2\) \[ =-393 \mathrm{~kJ} / \mathrm{mol} \] Standard enthalpy of formation of \(\mathrm{N}_2 \mathrm{O}\)…
