Question

Select all that apply. Atom A reacts with molecule BC according to the following reaction: 10 points A + BC → products If an atom of A collides with a molecule of BC, but no reaction occurs, what are the possible reasons why? Select all that apply. A. The reactants are moving too rapidly for the reaction to occur. B. There are too few of one of the reactants for the reaction to occur. c. The reactants did not collide in the right orientation. D. The reactants did not collide with enough kinetic energy.

Answer 1

According to the collision theory three things are required for rection to occur when two molecules/atoms collides:--

Molecules must collide in order to react.

In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds; this energy is known as the activation energy.

As the temperature rises, molecules move faster and collide more vigorously, greatly increasing the likelihood of bond breakage upon collision.

option a) is incoreect because if the they are moving very rapidly it will favour reaction because of high kinetic energy. b) is incorect fewer reactants may be the reason for low rate of reaction on a macro point of view but here in this question we are talking about a single atom and molecule interaction hence it doesn't matters.

Thus answer is c) d)
