Guten Abent!
1) Could you please post the source and if available online the address thereto?
To myself, this sadly doesn't speak about viability, yields obtained, methods of reaction or otherwise.
2) Below is a shitty translation, hope it helps.. and for your future ref, (I'm assuming you are yet familiar with translation software/websites),

7. The reaction of iodine with oxalic acid in aqueous solution runs after the following gross equation:
I2 + (COOH)2 2 HI + 2 CO2
The mechanism of the reaction contains two parallel reactions with the speed-determining,
Steps:
I + HC2 I- + HC2O4
HOI + HC2 I- + H2O + CO2
These two processes are coupled over equilibrium to the Edukte:
I2 2I K1 = ;
I2 + H2O HOI + I- + H+ K2 =
One assumes that the equilibrium adjust themselves in the comparison with the decomposition reactions fast and during the reaction remain preserved.
a) Indicate the speed law for the reaction.
b) Outline (verbal) the pH - dependence of the reaction.
c) Whereby the course of the iodine concentration is at constant, high pH - value and more
largely Initial concentration characterized by iodine, if K2 >> K1 and k2 > k1 applies?
