Nitric oxide can be made from the reaction of oxygen and nitrogen gases. O₂(g) + N₂(g) → 2NO(g)
If ΔG° = 165.5 kJ,and ΔH° = 180.4 kJ,what is ΔS° at 325°C?

Question

Nitric oxide can be made from the reaction of oxygen and nitrogen gases. O₂(g)+ N₂(g)→ 2NO(g) If ΔG° = 165.5 kJ,and ΔH° = 180.4 kJ,what is ΔS° at 325°C?

Quizplus · Accepted Answer

We can use the equation ΔG° = ΔH° - TΔS° to solve for ΔS°. First, we need to convert the given temperature of 325°C to Kelvin:

T = 325°C + 273.15 = 598.15 K

Then, we can rearrange the equation to solve for ΔS°:

ΔS° = (ΔH° - ΔG°)/T

ΔS° = (180.4 kJ - 165.5 kJ)/598.15 K = 0.0249 kJ/K

Therefore, the answer is B.
