Which is correct according to the collision theory of chemical reactions?

Options

  1. AA chemical reaction occurs with every molecular collision
  2. BRate is directly proportional to the number of collisions per second
  3. CReactions in the gas phase are always of zero order
  4. DReaction rates are of the order of molecular speeds

Correct answer

B. Rate is directly proportional to the number of collisions per second

Step-by-step solution

The increase in collision frequency brings in an increase in effective collisions and thus rate of reaction increases.
