Calculate the total entropy change for the following reversible processes: a. Isothermal b. Adiabatic

Entropy is a measure of randomess of system. When a liquid is converted to the vapour state entropy of the system increases. Entropy in the phase transformation is calculated using Delta S = (Delta H)/(T) but in reversible adiabatic process Delta S will be zero. The rise in temperature in isobaric or isochoric process increases the randomness of system, which is given by Delta S = "2.303 n C log"((T_(2))/(T_(1))) C = C_(P) or C_(V) Entropy change in a reversible adiabatic process is

Which of the following expression for entropy change of an irreversible process ?

The thermodynamic property that measures the extent of molecular disorder is called entropy. Entropy change of phase transformation can be calculated using Trouton's formula (DeltaS = DeltaH//T) . In the reversible adiabatic process, however, DeltaS will be zero. the rise in temperature in isobaric and isochoric conditions is found to increase the randomness or entropy of the system. DeltaS = 2.303 C log (T_(1)//T_(2)) The entropy change in an adiabatic process is

Entropy change in reversible adiabatic process is:

Consider the following statements: I. Change in enthalpy is always smaller than change in internal energy. II. The variation in enthalpy of a reaction with temperature is given by Kirchhoff's equation. III. The entropy change in reversible adiabatic process is equal to zero. Select the correct answer.

Entropy ( S ) is a thermodynamic variable like pressure P , volume V and temperature T . Entropy of a thermodynamic system is a measure of disorder of molecular motion. Greater is disorder , greater is entropy. Change in entropy of a thermodynamic system is the ratio of heat supplied to absolute temperature.In an adiabatic reversible process, entropy remains constant while in any irreversible process entropy increases. In nature the processes are irreversible , therefore entropy of universe is continuoulsy increasing. The unit of entropy in S-I system is -
