Which of the following can reduce decomposition of $\mathrm{H}_{2} \mathrm{O}_{2}$ on exposure to light :
Solution
Urea is a negative catalyst, which means that it slows down the rate of a chemical reaction. In the case of hydrogen peroxide, urea absorbs the light that would otherwise cause it to decompose. This prevents the reaction from happening, or at least slows it down significantly.
