Question

Carbon monoxide and nitrogen monoxide react to produce carbon dioxide and nitrogen gas. If the
system contains platinum, then less energy is required for the reaction to occur. Which term best
describes the role of platinum in the system? (1 point)
catalyst
reactant
product
energy

Answer 1

The term that best describes the role of platinum in the system is **catalyst**. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, and it often lowers the energy required for the reaction to occur.
