Pick out the wrong statement?

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.CA.CB, then the reaction is always
elementary
