Question

All the naturally occurring processes proceed spontaneously in a direction which leads to

• A. Increase in enthalpy of system
• B. Decreases in entropy of system
• C. Increase in entropy of system
• D. Increse in entropy of Universe

Answer 1

Answer: (D)

Increse in entropy of Universe

The second law of thermodynamics states that the entropy of an isolated system never decreases, because isolated systems spontaneously evolve toward thermodynamic equilibrium the state of maximum entropy.

Therefore, all the naturally occurring processes proceed spontaneously in a direction which leads to increase in entropy of universe.
