Final answer:
Manganese dioxide as a catalyst accelerates the production of oxygen gas from hydrogen peroxide by lowering the activation energy of the reaction.
Explanation:
The speed of the chemical reaction increases significantly when manganese dioxide is used as a catalyst instead of glycerin in the process of generating oxygen gas from hydrogen peroxide. The catalyst provides an alternate reaction pathway with a lower activation energy barrier, speeding up the decomposition of hydrogen peroxide into oxygen and water.
The catalyst actively participates in the chemical reaction by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate without getting consumed.
Therefore, the manganese dioxide catalyst plays a crucial role in accelerating the production of oxygen gas from hydrogen peroxide by facilitating the reaction and speeding up the decomposition process.
