What is the role of glycerol in the decomposition of hydrogen peroxide?
- AIt increases the reaction rate.
- Correct answerBIt reduces the reaction rate.
- CIt increases the enthalpy of the reaction.
- DIt increases the rate of collisions between reactant molecules.
Solution
Hydrogen peroxide ($H_2O_2$) decomposes into water and oxygen gas upon standing or heating.
To prevent or slow down this decomposition, certain substances are added which act as negative catalysts (inhibitors).
Glycerol, along with urea and acetanilide, is commonly used as a stabilizer for hydrogen peroxide. It acts as a negative catalyst and retards the decomposition process.
Therefore, glycerol reduces the reaction rate of the decomposition of hydrogen peroxide.
Answer: It reduces the reaction rate.
