Question

Substances burn more readily in $N_{2}O$ than in air because $N_{2}O$ :

• A. is reactive at high temperature.
• B. dissociates to give $O_2$ that supports combustion.
• C. the activation energy is increased on increasing temperature.
• D. acts as a catalyst.

Answer 1

The correct option is B dissociates to give $O_2$ that supports combustion.

Reaction:
$2N_{2}O\to 2N_2+O_2$
as it gives $O_2$ so burning happens here more easily.
