Consider the reaction 2N2(g) O2(g)2N2O(g) Using the standard thermodynamic data in the tables linked above, calculate Grxn for this reaction at 298.15K if the pressure of each gas is 22.20 mm Hg.

ΔG ≅ 199.91 kJ

Explanation:

Consider the reaction:

temperature = 298.15K

pressure = 22.20 mmHg

From, The standard Thermodynamic Tables; the following data were obtained

The equilibrium constant determined from the partial pressure denoted as can be expressed as :

= 0.045

where;

R = gas constant = 8.314 × 10⁻³ kJ

199.912952  kJ

ΔG ≅ 199.91 kJ
