According to collision theory, for a reaction to be successful, it must have correct orientation of the atoms of the reactants. Which of the following must also be present for a successful reaction to occur?
a catalyst
sufficient energy
adequate velocity
high molecular mass
Answers
Answer: Option (b) is the correct answer.
Explanation:
Collision theory states that for a reaction to occur, it is required that the reactants or reacting species must come together and colloid with one another.
This is only possible when sufficient amount of energy is provided to the reactant species.
Whereas a catalyst increases the rate of a reaction by changing its path but it does not provide energy to the species which is necessary for completion of a reaction.
High velocity is only possible if atoms have some amount of energy because without energy atoms cannot achieve high velocity. On the other hand, if atoms have high molecular mass then they will have difficulty to move from one place to another.
Thus, sufficient amount of energy must be provided in the reaction for its successful completion.
