Which will cause an increase in the reaction rate between molecules? molecules have strong internal bonding. molecules collide more frequently. electrons in the bonds remain in a meta-stable state. electrons do not have enough energy to leave the bonds.

Option (b) is the correct answer.

Explanation:

According to collision theory, more is the number of collisions between molecules of reactants more quickly the reaction will result in the formation of products.

Whereas rate of reaction is defined as the speed of molecules with which they come in contact with each other and other molecules.

Thus, we can conclude that when molecules collide more frequently then it will cause an increase in the reaction rate between molecules.
