Question: According to the collision theory of chemical reactions
Options:
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
