Question

Calculate ΔGrxn for this equation
A) 2n2(g) + o2(g) 2n2o(g)

Answer 1

The ΔGrxn for the reaction 2N₂(g) + O₂(g) → 2N₂O(g) is calculated using the formula ΔGrxn = ΔH° - TΔS, yielding a result of –32.7 kJ per mole of N₂.

Step-by-step explanation:

To calculate ΔGrxn for the reaction 2N₂(g) + O₂(g) → 2N₂O(g), we will use the formula ΔGrxn = ΔH° - TΔS. Given the enthalpy change (ΔH°) and the entropy change (ΔS) for the reaction, we can insert the values into the equation as shown:

ΔGrxn = (–91.8 kJ) – (298 K)(–198.1 J/K)(1 kJ/1000 J) = –32.7 kJ

This result represents the Gibbs free energy change for the reaction per mole of N₂.
