Chemical Engineering Thermodynamics If we increase the pressure on a substance (which is at its triple point), then the triple point Increases Decreases Remains unchanged May increase or decrease ; depends on the substance Increases Decreases Remains unchanged May increase or decrease ; depends on the substance ANSWER DOWNLOAD EXAMIANS APP
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 only Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi Temperature only Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi ANSWER DOWNLOAD EXAMIANS APP
