Nitrogen molecules rest with oxygen molecules. Nitrogen monoxide molecules are made.

N2 + O2 → 2NO

Nitrogen molecules and oxygen molecules react extremely slowly, even at 200°C.

The reaction between nitrogen

and oxygen becomes faster as both the temperature and the pressure increase. Explain why, using the reacting

particle model. (6 marks)

At high temperature and pressure, reactions become faster

Explanation:

Collision theory or reaction particle model state that reacting particles must collide before reactions occur.

Reaction rate of reaction is dependent on the frequency of collision.

Kinetics of gases increases at higher temperature and pressure.

As the temperature and pressure of nitrogen and oxygen increased, they bound to move more faster, collide more frequently as to attain activation energy easily thereby increasing the reaction rate or making the reaction to complete faster.

Also at higher pressure, gaseous reactants are closer to each other.
