Which condition will cause a reaction to occur? check all that apply.

particles and molecules must collide.

collisions must be energetic enough to overcome the activation barrier.

collisions must be properly oriented for the relevant parts to react.

the energy needed to overcome the activation energy comes from the kinetic energy of random collisions.

All options are correct.

Explanation:

Chemical reaction may be defined as the reaction in which the substance known as reactant under goes the change and finally converted into the product. The chemical reaction must shows some changes during the reaction like evolution of gas and color change.

The substance that takes part in the chemical reaction must collide with each other. The collision must be properly oriented and must overcome the activation barrier of the reaction. The kinetic energy of the random collision must be greater than the activation energy.

Thus, all the given options are correct.
