Explanation:
Nitric oxide (nitrogen oxide[3] or nitrogen monoxide) is a colorless gas with the formula NO. It is one of the principal oxides of nitrogen. Nitric oxide is a free radical, i.e., it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (·N=O or ·NO). Nitric oxide is also a heteronuclear diatomic molecule, a historic class that drew researches which spawned early modern theories of chemical bonding.[4]
Answer:
Positive catalyst: A catalyst which increases the rate of reaction is called positive catalyst. Such catalyst decreases activation energy by accepting a smaller path, so rate of reaction is increased. Negative catalyst (Inhibitor): A catalyst which decreases or retards the rate of reaction is called negative catalyst.
