Which of the following is true for a reaction as per collision theory?

Which of the following is true for a reaction as per collision theory?
  1. Every collision between reactants leads to chemical reaction.
  2. It may be expected that rate of reaction is equal to rate of collision.
  3. For gas phase reactions, the number of collisions is far less compared to observed rate.
  4. The colliding molecules do not need proper orientation.

Solution

Not every collision between reactants leads to a chemical reaction. For gas phase reactions, the number of collisions is more as compared to the observed rate. The colliding molecules need proper orientation.
