Catalysis in Redox Reactions
- A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
- A positive catalyst specifically speeds up the reaction, while a negative catalyst (inhibitor) slows it down.
- An auto catalyst is a product of the reaction that also acts as a catalyst, accelerating the reaction further.
EXPLANATION:
- In the reaction KMnO4 + H2SO4 + H2C2O4 → Products, Mn2+ ions are produced as the reaction proceeds.
- These Mn2+ ions then catalyze the decomposition of oxalic acid (H2C2O4) and the reduction of KMnO4, which accelerates the reaction.
- Since Mn2+ ions are a product of the reaction and also act as a catalyst, they are referred to as an autocatalyst.
CONCLUSION:
The correct answer is: Auto-catalyst
