(NOS) +18) - NOX

Answer 1

To calculate the enthalpy change (ΔH) for the reaction, we need to consider the enthalpies of formation (∆Hf) of the reactants and products. The enthalpy change (∆H) can be calculated using the following equation:

ΔH = Σ(∆Hf(products)) - Σ(∆Hf(reactants))

Given the balanced chemical equation:

2NO(g) + O3(g) -> 3O2(g) + 2NO2(g)

The enthalpy change (∆H) can be calculated as follows:

ΔH = [3∆Hf(O2)] + [2∆Hf(NO2)] - [2∆Hf(NO)] - ∆Hf(O3)

To calculate the values, we'll need the enthalpy of formation for each compound involved. Unfortunately, the enthalpy of formation values for NO, O2, O3, and NO2 are not provided in your question. These values can vary depending on the conditions and reference state used. Please provide the specific values for the enthalpies of formation to calculate ΔH accurately.
