Question

Which is correct according to the collision theory of chemical reactions? (A) A chemical reaction occurs with every molecular collision (B) Rate is directly proportional to the number of collisions per second (C) Reactions in the gas phase are always of zero order (D) Reaction rates are of the order of molecular speeds

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

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

A chemical reaction occurs with every molecular collision

Rate is directly proportional to the number of collisions per second

Reactions in the gas phase are always of zero order

Reaction rates are of the order of molecular speeds

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