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 Differential heat of adsorption Heat of wetting None of these Integral heat of adsorption Differential heat of adsorption Heat of wetting None of these Integral heat of adsorption ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Relative volatility varies with the concentration of component for an ideal solution. The relative volatity of a binary mixture may be defined as the ratio of vapor pressure of component 'A' to that of component 'B', when Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only vapor phase follows Raoult's law Vapor phase obeys Dalton's law and liquid phase obeys Raoult's law Only liquid phase obeys Dalton's law Liquid phase obeys Dalton's law and vapor phase obeys Raoult's law Only vapor phase follows Raoult's law ANSWER DOWNLOAD EXAMIANS APP
