Question

1. In order for a chemical reaction to occur, there
must always be
(1) an effective collision between reacting particles
(2) a bond that breaks in a reactant particle
(3) reacting particles with a high charge
(4) reacting particles with high kinetic energy

Answer 1

Answer:

(3)

Explanation:

Answer 2

For a chemical reaction to occur there must be:

(1) an effective collision between reacting particles

What all is needed for a chemical reaction to occur?

The chemical reactions occur when chemical bonds between atoms are formed or broken. Molecules must collide. Molecules must collide with enough energy to begin to break the old bonds so new bonds can form. ( Remember activation energy). Molecules must collide with the correct orientation.

Thus, correct option is 1.
