Q. The activation energy of a reaction is zero. The rate constant for the reaction
A) Decreases with decrease of temp
B) Increases with increase of temp
C) Decreases with increase of temp
D) Is nearly independent of temp
Explanation
(d)
If $E_{a} = 0,\ k = Ae^{- E_{a}/RT} = Ae^{0} = A$
Hence, $k$ becomes independent of $T$
