Solution

The correct option is D Both Assertion and Reason are incorrect
Only effective collisions result into product formation i.e. collisions in which molecules collide with sufficient kinetic energy (called threshold energy) and proper orientation, so as to facilitate breaking of bonds between reacting species and formation of new bonds to form products.
