Chemical Engineering Thermodynamics Which of the following equations is obtained on combining 1st and 2nd law of thermodynamics, for a system of constant mass? DE = Tds - PdV DQ = CvdT + PdV DQ = CpdT + Vdp Tds = dE - PdV DE = Tds - PdV DQ = CvdT + PdV DQ = CpdT + Vdp Tds = dE - PdV 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 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
