Question

Even if two substances have enough energy to react during a collision, they will not react unless  Question 1Select one: a. the proper catalyst is present. b. the substances are in the proper orientation. c. the reaction is exothermic and gives off energy. d. the activation energy of the reaction is lowered.

Answer 1

The substances must be in the proper orientation for a reaction to occur during a collision.

Step-by-step explanation:

The correct answer to the question is option b. the substances are in the proper orientation.

In order for two substances to react during a collision, they must be in the proper orientation. This means that the atoms or molecules involved in the reaction must collide in a way that allows their bonding sites to come into contact with each other. If the orientation is not correct, the reaction will not occur.

While the presence of a catalyst or the exothermic nature of the reaction can influence the speed or direction of a reaction, they are not necessary for a reaction to occur. Similarly, the activation energy of the reaction refers to the minimum amount of energy required to initiate the reaction, but it does not determine whether a reaction will happen or not.
