Question
a.
In a first order reaction, A → products; the reaction becomes slower as it proceeds, because the concentration of A decreases and the rate is proportional to the concentration of A.
b.
Transition state theory approaches the problem of calculating reaction rates by concentrating on the idea of activated complexes.
c.
According to the penetration theory, the mass transfer co-efficient decreases, if the exposure time of an eddy to the solute decreases.
d.
If the rate of an irreversible reaction, A + B → 2C is k.Cᴀ.Cʙ, then the reaction is always elementary.
