Calculate ΔrG for conversion of oxygen to ozone, 3/2 O2(g) → O3 (g) at 298 K, if Kp for this conversion is 2.47 x 10^-29. ​

Question

Calculate Δ_rG for conversion of oxygen to ozone, \(\frac{3}{2}\) O₂(g) → O₃ (g) at 298 K, if K_p for this conversion is 2.47 x 10^-29.

Answer 1

Given, T = 298 K

K_p = 2.47 × 10⁻²⁹

∆_rG^Θ = ?

\(\because\) ∆_rG^Θ = −2.303 RT log K_p

= −2.303 × (8.314 J K⁻¹ mol⁻¹ ) × (298 K) × log(2.47 × 10⁻²⁹)

= 163000 J mol⁻¹

= 163 kJ mol⁻¹
