Q. All movements and collisions in the molecules irrespective of their energy and direction causes chemical change.

Which of the following statements is incorrect about the collision theory of chemical reaction?

(a) It considers reacting molecules or atoms to be hard spheres and ignores their structural features
(b) Number of effective collisions determines the rate of reaction
(c) Collision of atoms or molecules possessing sufficient threshold energy results into the product formation
(d) Molecules should collide with sufficient threshold energy and proper orientation for the collision to be effective

Q. Assertion :All molecular collisions lead to the formation of products. Reason: Reactant molecules undergo chemical change irrespective of their collision.

Explain:

The molecules during collisions attain threshold energy and only then they result in chemical reaction. Certain collisions inspite of possessing thr es hold energy do not result in chemical reactions. This is because the orientation of collisions is not suitable for a chemical reaction. Thus, the collisions which are associated with threshold energy and
proper orientation only result in chemical reaction.

The __ of a chemical reaction is defined as the change in the concentration of any one of the reactants or product per unit time.
