An Irreversible process is one in which heat is transferred through a finite temperature. The questions cover following areas of Thermodynamics, ... Third law of thermodynamics; 3.What is thermodynamic system? decrease, Experts are waiting 24/7 to provide step-by-step solutions in as fast as 30 minutes!*. I2(s) + 2e-  2I-(aq) The third law (Nernst's theorem) actually states that the entropy of any system at absolute zero may always be taken as zero. ANSWER: The Third Law of Thermodynamics is the lesser known of the three major thermodynamic laws. E° (V) If acidic or basic, of a system is Calculate... A: P1, T1, V1 of ideal gas whose P2 is to be determined. If the ground state is degenerate (i.e., more than one state at the lowest energy level), then the entropy will approach a positive constant. Ans: b. conserved 3) In a crystalline state, there is a tendency to minimize entropy. Irreversible process is also known as spontaneous process because these processes take place at very fast rate. Following is the diagram of the thermodynamic process. Median response time is 34 minutes and may be longer for new subjects.
