Question

APTITUDE CRACK · Accepted Answer

The correct option is  A K &prop; D The correct relation according to film theory between mass transfer coefficient (&#119870;K) and diffusivity (&#119863;D) is: &#119870;&prop;&#119863;K&prop;D This implies that the mass transfer coefficient is directly proportional to the diffusivity. In other words, as the diffusivity of the species increases, the mass transfer coefficient also increases, and vice versa. So, the correct option is: &#119870;&prop;&#119863;K&prop;D
