Simultaneous pressure & temperature change Cooling Both B and C Heating Simultaneous pressure & temperature change Cooling Both B and C Heating 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 Le-Chatelier principle Kopp's rule Arrehenius hypothesis Law of corresponding state Le-Chatelier principle Kopp's rule Arrehenius hypothesis 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 0.1 Partially condensed vapour with quality of 0.9 Superheated vapour Saturated vapour Partially condensed vapour with quality of 0.1 Partially condensed vapour with quality of 0.9 Superheated vapour Saturated vapour ANSWER DOWNLOAD EXAMIANS APP
