Question

Write any two factors for effective collision

Answer 1

Answer:

#Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break.

# Molecules must collide with the proper orientation.

A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision
