An example for auto-catalysis is
- A oxidation of \(\mathrm{NO}\) to \(\mathrm{NO}_{2}\)
- B oxidation of \(\mathrm{SO}_{2}\) to \(\mathrm{SO}_{3}\)
- C decomposition of \(\mathrm{KClO}_{3}\) to \(\mathrm{KCl}\) and \(\mathrm{O}_{2}\)
- D oxidation of oxalic acid by acidified \(\mathrm{KMnO}_{4}\)
Answer & Solution
Correct Answer
(D) oxidation of oxalic acid by acidified \(\mathrm{KMnO}_{4}\)
Step-by-step Solution
Detailed explanation
An example of auto-catalysis is oxidation of oxalic acid by acidified \(\mathrm{KMnO}_{4}\) solution. In this reaction, one of the product \(\left(\mathrm{Mn}^{2+}\right)\) formed act as a catalyst and speed up the reaction.…
