Step-by-step solution

Given, (K_p ) for the conversion of oxygen to ozone at (400 ~K ) is (1.0 10⁻³⁰ ). ( ( G^ ) ) standard Gibbs energy change (= ) ? ( G^ =-R T K_p=2.303 R T ₁₀ K_p ) Here, (R=8.314 ~J / mol ) ( aligned T & =400 ~K G^ & =-R T K_p & =-8.314 400 2.303 10⁻³⁰ & =22976570 ~J ~mol ⁻¹ & =229.765 ~kJ ~mol ⁻¹ aligned )
