Problem: Given the data in the table below, ΔH°rxn for the following reaction is __________ kJ.3NO2(g) + H2O(l) → 2HNO3 (aq) + NO (g)A) 64B) 140C) -140D) -508E) -64
FREE Expert Solution
We’re being asked to determine the standard enthalpy change of reaction. Recall that ΔH˚rxn can be calculated from the enthalpy of formation (ΔH˚f) of the reactants and products involved:
We’re given the ΔH˚f for each species. The chemical equation for that reaction is:
3 NO2(g) + H2O(l) → 2 HNO3 (aq) + NO (g)
This equation is already balanced.
Given the data in the table below, ΔH°rxn for the following reaction is __________ kJ.
3NO2(g) + H2O(l) → 2HNO3 (aq) + NO (g)
