Rate of Reactions Quiz

If the temperature at which a reaction occurs increases, the number of collisions decreases.

• True

• False

The rate of a chemical reaction is defined as the change in concentration of a reactant or product in a given time interval

• True

• False

The collision theory states that atoms, ions, and molecules must collide in order to react.

• True

• False

Orientation of molecules during a reaction does not affect the production of products.

• True

• False

The potential energy of an activated complex is at a maximum.

• True

• False

The minimum amount of energy needed by the reactant to form the activated complex and lead to a reaction is known as the activation energy.

• True

• False

According to the rate law, the reaction rate is directly proportional to the molar concentration of the reactant.

• True

• False

The rate of a chemical reaction is unrelated to the spontaneity of the reaction.

• True

• False
