The equation representing the decomposition of hydrogen peroxide is given below. $2\text{H}_2\text{O}_2 \rightarrow 2\text{H}_2\text{O} + \text{O}_2$ This reaction is exothermic. If a small amount of catalyst is added, oxygen is formed at a faster rate. Which statement correctly describes the catalyst?
- AThe catalyst makes the reaction more exothermic.
- BThe mass of catalyst is the same before and after the reaction.
- CThe catalyst increases the final volume of oxygen produced.
- DAll of the catalyst is used up in the reaction.
