Chemical Engineering Thermodynamics A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is Φi yi P = Yi xi fi° where, Φ is a vapor fugacity component, Yi is the liquid activity co-efficient and fi° is the fugacity of the pure component i. the Ki value (Yi = Ki xi) is therefore, in general a function of Temperature, pressure and liquid composition xi only Temperature, pressure, liquid composition xi and vapour composition yi Temperature and pressure only Temperature only Temperature, pressure and liquid composition xi only Temperature, pressure, liquid composition xi and vapour composition yi Temperature and pressure only Temperature only ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics In the reaction, H₂ +I₂ ⇋ 2HI, addition of an inert gas will Increase the total pressure and hence shift the equilibrium towards the right Not effect the equilibrium conditions Increase the partial pressure of I₂ Increase the partial pressure of H₂ Increase the total pressure and hence shift the equilibrium towards the right Not effect the equilibrium conditions Increase the partial pressure of I₂ Increase the partial pressure of H₂ ANSWER DOWNLOAD EXAMIANS APP
