Q. Chemical reactions with very high $E_{a}$ values are generally
A) Very fast
B) Very slow
C) Moderately fast
D) Spontaneous
Explanation
(b)
Reactions having low $E_{a}$ are fast reactions and reactions having high $E_{a}$are slow reactions.
If the $E_{a}$ is high, then the number of effective collisions will be small and the reaction will be slow.
