Question

Given the data in the table below, ΔH°_rxn for the reaction 3NO₂ (g)+ H₂O (l)→ 2HNO₃ (aq)+ NO (g) Is __________ kJ.

Quizplus · Accepted Answer

From the given data, ΔH°_rxn = -140 kJ. The negative sign indicates that the reaction is exothermic, which means that heat is released during the reaction. Therefore, the correct answer is C, -140 kJ.
