Mass Transfer The change in enthalpy, when a unit quantity of gas is absorbed by relatively large quantity of adsorbent (on which a definite concentration of the adsorbed gas already exists) is termed as the Integral heat of adsorption Differential heat of adsorption None of these Heat of wetting Integral heat of adsorption Differential heat of adsorption None of these Heat of wetting ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Steam distillation is not recommended to be used, if the Liquids decompose, if distilled directly at atmospheric pressure Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Liquids decompose, if distilled directly at atmospheric pressure Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer A pure drug is administered as a sphere and as a cube. The amount of drug is the same in the two tablets. Assuming that the shape and size do not influence the mass transfer, the ratio of rate of dissolution in water at t = 0 for the cubic to spherical tablet is 0.54 1.24 1.94 1.04 0.54 1.24 1.94 1.04 ANSWER DOWNLOAD EXAMIANS APP
