What are the products of 1 mol of vitamin C (C6H8O6) and 1 mol of hydrogen peroxide (H2O2)?

Basic stoichiometry suggests that $\pu{1 mol}$ of vitamin C($\ce{C6H8O6}$) react with $\ce{1 mol}$ hydrogen peroxide ($\ce{H2O2}$) to produce one $\ce{1 mol}$ dehydroascorbic acid DHA($\ce{C6H6O6}$)?

Other sources suggest that the product of the above chemical reaction DHA ($\ce{C6H6O6}$), is more susceptible to further oxidation than vitamin C ($\ce{C6H8O6}$), leading to further reduction.


[("Both dehydroascorbic acid and hydrolyzed dehydroascorbic acid (diketogulonic acid) are more susceptible to hydrogen peroxide oxidation than ascorbic acid.")](https://%20https://pubmed.ncbi.nlm.nih.gov/9448835/)


**Would the reaction change if it took place in 1 liter of $\ce{H2O}$?**
**How could I control the reaction to produce DHA?**
