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 Arrehenius hypothesis Kopp's rule Le-Chatelier principle Law of corresponding state Arrehenius hypothesis Kopp's rule Le-Chatelier principle Law of corresponding state ANSWER DOWNLOAD EXAMIANS APP

Chemical Engineering Thermodynamics Steam undergoes isentropic expansion in a turbine from 5000 kPa and 400°C (entropy = 6.65 kJ/kg K) to 150 kPa) (entropy of saturated liquid = 1.4336 kJ/kg . K, entropy of saturated vapour = 7.2234 kJ/kg. K) The exit condition of steam is Partially condensed vapour with quality of 0.9 Saturated vapour Partially condensed vapour with quality of 0.1 Superheated vapour Partially condensed vapour with quality of 0.9 Saturated vapour Partially condensed vapour with quality of 0.1 Superheated vapour ANSWER DOWNLOAD EXAMIANS APP
