The initial step in the industrial manufacture of nitric acid starting from ammonia is shown by this equation. $4\text{NH}_3(\text{g}) + 5\text{O}_2(\text{g}) \rightleftharpoons 4\text{NO}(\text{g}) + 6\text{H}_2\text{O}(\text{g})$ By using the standard enthalpy change of formation data below, determine the value of the standard enthalpy change, $\Delta H^\circ$, for this reaction.
- A$+905.2\,\text{kJ mol}^{-1}$
- B$-105.4\,\text{kJ mol}^{-1}$
- C$-905.2\,\text{kJ mol}^{-1}$
- D$-1274.0\,\text{kJ mol}^{-1}$
