Question
The following equilibrium constants have been determined for oxalic acid at 25°C:
H2C2O4(aq) 2 H*(aq) + HC20, (aq) K = 6.5 × 10-2
HC2O, (aq) 2 H* (aq) + C20- (aq) K" =
6.1 × 10-5
Calculate the equilibrium constant for the following reaction at the same temperature:
H2C2O4(aq) 2 2H* (aq) + C20 (aq)
