COLLISION THEORY AND CHEMICAL REACTION RATE

Question 1

All substances are composed of millions of tiny particles in constant motion. These particles are colliding with each other constantly in any substance.

Answer 1

The Collision Theory

Question 2

Two Factors that determine whether a reaction will occur between two particles that are colliding:

Answer 2

Substances or particles of reactants must physically collide with enough energy.
Substance or particles must come in contact or collide in the correct orientation.

Question 3

The ___________ _________ states that reacting substances must come in contact (collide) with enough activation energy, and in the correct orientation, so that their electron shells can rearrange to form the products of the reaction.

Answer 3

Collision Theory

Question 4

___________ __________ are collision of particles that result into a chemical reaction. For an ___________ __________ to happen particles of the reactant must have at least the minimum energy required to break the bond of the reactants, known as the activation energy.

Answer 4

Effective collisions

Question 5

When two particles collide, sometimes a ___________ __________ occur, which means the bonds between two or more particles are broken and reformed, creating one or more new substances
