A spontaneous process is simply a process which is feasible. The first law of thermodynamics confirms that there has been no change in the system’s internal energy as a result of this process. By expanding consideration of entropy changes to include the surroundings, we may reach a significant conclusion regarding the relation between this property and spontaneity. Definition: The Second Law of Thermodynamics All spontaneous changes cause an increase in the entropy of the universe. Solution Verified by Toppr Correct option is C) According to the law of entropy (also known as the second law of thermodynamics), the entropy for the spontaneity of any process is always accompanied by an increase in total entropy of the universe i.e. Home Class 11 Chemistry Thermodynamics Spontaneous and Non-spontaneous Process. Processes that involve an increase in entropy of the system (Δ S > 0) are very often spontaneous however, examples to the contrary are plentiful. of a process at constant pressure and temperature. A process that is spontaneous in one direction under a particular set of conditions is nonspontaneous in the reverse direction. In the quest to identify a property that may reliably predict the spontaneity of a process, we have identified a very promising candidate: entropy. The change in the Gibbs Free Energy (G) alone p rovides a criterion for the spontaneity. Equation for the total change in entropy Gibbs Energy and Spontaneity A new thermodynamic function. ![]() ![]() Calculate entropy changes for phase transitions and chemical reactions under standard conditions S State and explain the second and third laws of thermodynamics. ![]()
