Question

Calculate ∆_rGe for conversion of oxygen to ozone 3/2 O_2(g) → O_3(g) at 298 K_p If for this conversion is 2.47 x 10^-29.

Answer 1

We know

∆_rG^⊖ = -2.303 RT log K_p

R = 8.314 JK^-1 mol^-1 

∆_rG^⊖ = -2.303 (8.314 J K^-1 mol^-1 ) x (298 K) (log 2.47 x 10^-29 ) 

= 163000 J mol^-1 

= 163 mol^-1
