###### Problem Details

The following equilibrium constants have been determined for oxalic acid at 25 °C.

H2C2O4 (aq) ⟺ H+ (aq) + HC2O- (aq)    K= 6.5 x 10 -2

HC2O4- (aq) ⟺ H+ (aq) + C2O2- (aq)        K = 6.1 x 10 -5

Calculate the equilibrium constant for the following reaction at the same temperature:

C  2O2− + 2H + ⟺ H2C2O4 (aq)
