Question

Which statement best applies collision theory to preventing a dangerous reaction from occurring? Store the reactants together at a low pressure. Keep all sparks or flames away from the reactants. Store the reactants together at a low temperature. Keep the reactants in separate containers.

Answer 1

Answer:

According to collision theory, to preventing a dangerous reaction from occurring, the best is to keep reactants in separate containers (last statement).

Justification:

Collison theory states that the the reactant substances (atoms, ions or molecules) must first collide to react and form the products.

Additionally, to form the products, the collisions must meet two requirements:

• the reactant substances must collide with the correct orientation, and

• the reactant substances must collide with energy enough to form the activated complex (transition state).

Hence, the collision theory permits you preventing a dangerous reaction from occurring, by using the elemental knowledge that the substances must first collide in order to they react, and so the most effective way is to keep the reactants in separate contaners, preventing the reactants from coming into direct contact.

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

According to collision theory, the particles should colloid frequently and they should be placed in proper orientation.

Whereas sometimes even at low temperature, reactant particles have enough energy. As a result, they tend to colloid or react with each other. Hence, it leads to a chemical reaction which might be dangerous.

Therefore, it is suitable to keep the reactant particles in separate containers so that a chemical reaction cannot take place.

So, we can conclude that the statement keep the reactants in separate containers best applies collision theory to preventing a dangerous reaction from occurring.
