Chemical Engineering Thermodynamics Law of corresponding states says that The surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature No gas can be liquified above the critical temperature, howsoever high the pressure may be The molar heat of energy of gas at constant volume should be nearly constant (about 3 calories) , two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same The surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature No gas can be liquified above the critical temperature, howsoever high the pressure may be The molar heat of energy of gas at constant volume should be nearly constant (about 3 calories) , two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same ANSWER DOWNLOAD EXAMIANS APP

Chemical Engineering Thermodynamics When a system in equilibrium is subjected to a change in temperature, pressure or concentration, the equilibrium is displaced in a direction which tends to undo the effect of the change. This is called the Law of corresponding state Le-Chatelier principle Arrehenius hypothesis Kopp's rule Law of corresponding state Le-Chatelier principle Arrehenius hypothesis Kopp's rule ANSWER DOWNLOAD EXAMIANS APP
