Question

in chemical reaction only some collisions between molecules are effective explain why?​

Answer 1

In producing a chemical reaction, only some collision between molecules are effective. ... Some collisions are not energetic enough to cause a reaction so they are ineffective. Some collisions are on the wrong part of the molecule or the wrong orientation and even if they have enough energy, there will be no reaction.

Answer 2

Answer:

In chemical reaction only some collisions between molecules are effective - Reason was given below.

Explanation:

• The rate of the chemical reactions was predicted by the Collision theory.
• Based on the Collision theory for the reaction to occur the reacting molecules should collide or come in contact with each other.
• Therefore the chemical change cannot be brought only by collision.

In chemical reaction only some collisions between molecules are effective:

Reason:

• The chemical reaction will occur in a effective if the two reacting species should have minimum internal energy and activation energy for the reaction.
• For the rearrangement of atoms and electrons in the reacting species the colliding molecules should be oriented.
• Collision theory states that the rate at which the chemical reaction proceeds is equal to the Frequency of the collision.
• If the collision energy is equal or greater than the activation energy the chemical reaction will occur effectively or else some collision between the molecules will not result in collision
• During chemical reaction the bonds in the reacting species get break and new molecule will be formed.
