What is the enthalpy of the overall chemical equation NO(g) + O(g) Right arrow. NO(g)?
-305 kJ
-304.1 kJ
-93.7 kJ
588.7 kJ

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
