The decomposition of \mathrm{NH}_{3} on gold and molybdenum surface is an example for zero order reaction.

Answer: Option C

Explanation:

Zero order reaction can be termed as a type of reaction where the rate is not dependent on the concentration of the provided reactants. In other words, it can be described as, the rate of the reaction is directly proportional to the \bold{\mathrm{0}^{\mathrm{th}}} power of concentration of the provided reactants.  

For example, the catalysts surface (gold or molybdenum) is covered by \mathrm{NH}_{3} molecules and its concentration remains even when the product formation is done. Thus it is an example of zero order reaction.
