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