Gaseous nitrosyl chloride (NOCl) is injected in a 1.0-L container where it starts decomposing irreversibly. 2NOCl(g) → 2NO(g) + Cl2(g) The container is insulated (no heat exchange with its surroundings) and has a movable part that allows one to change its volume. Before the reaction is over, the container’s volume is abruptly increased to 1.5 L. Use collision theory to explain how this will affect the rate at which NOCl decomposes.
- Gaseous nitrosyl chloride (NOCl) is injected in a 1.0-L container where it starts decomposing irreversibly.

The container is insulated (no heat exchange with its surroundings) and has a movable part that allows one to change its volume. Before the reaction is over, the container’s volume is abruptly increased to 1.5 L. Use collision theory to explain how this will affect the rate at which NOCl decomposes.
Chemical kinetics is the branch of chemistry that mainly deals with the rate of reaction and change in the concentration of reactant and product molecules with time.
The rate of reaction expresses by the rate law which states that the rate of reaction is directly proportional to the active concentration of reactant molecules.
In the given reaction, the volume increases from 1.0 L to 1.5 L. It will reduce the pressure of the reaction mixture because the volume is inversely proportional to the pressure of the gas.
