Chemical Engineering Thermodynamics Number of components (C), phase (P) and degrees of freedom (F) are related by Gibbs phase rule as P + F - C = 2 P = F - C - 2 C = P - F + 2 F = C - P - 2 P + F - C = 2 P = F - C - 2 C = P - F + 2 F = C - P - 2 ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics It is desired to bring about a certain change in the state of a system by performing work on the system under adiabatic conditions. The amount of work needed is independent of path More information is needed to conclude anything about the path dependence or otherwise of the work needed Work alone can not bring out such a change of state The amount of work needed is path dependent The amount of work needed is independent of path More information is needed to conclude anything about the path dependence or otherwise of the work needed Work alone can not bring out such a change of state The amount of work needed is path dependent 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 Law of corresponding state Kopp's rule Le-Chatelier principle Arrehenius hypothesis Law of corresponding state Kopp's rule Le-Chatelier principle ANSWER DOWNLOAD EXAMIANS APP
