Question 14

In a laboratory simulation, particles of gas X collide with particles of gas Y. One collision has less energy than the activation energy.

What happens in this collision?

[1]
A

The particles form products because any collision causes a reaction

B

The particles bounce apart and no reaction happens

C

The particles bounce apart, and the activation energy is lower for later collisions

D

The particles take in energy from the surroundings and form products
