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

Text Solution

Verified by Experts

The correct Answer is:
B
The increase in collision frequency brings in an increase in effective collisions and thus rate of reaction increases .
