Free expansion ||Second Law OF Thermodynamics

I. Read the following passage and answer questions 1-5 that follows: Spontaneity means the feasibility of a reaction.Gibbs free energy (G) is the thermodynamic quantity which helps in predicting the spontaneity of a process G = H - TS The change in free energy is represented by Gibbs Helmoltz equation, DeltaH - DeltaH - TDeltaS For spontaneity of a process, DeltaG must be negative.It depends upon energy factor (DeltaH) and entropy factor (TDeltaS) . 1. What are the signs of DeltaH and DeltaS for the reactions : 2CI(g) to CI_(2)(g) ?

The first law of thermodynamics is based on the law of conservation of

Which statement is true about 2nd law of Thermodynamics

Assertion (A): The thermodynamic factor which determines the spontaneity of a process is the free energy. For a process to be spontaneous the free energy must be-ve. Reason (R ) : The change in free energy is related to the change in a process must always be positive if its is spontaneous.

According to the second law of thermodynamics, a process (reaction) is spontaneous, if during the process

The transfer of energy from one trophic level to another is governed by the 2nd law of thermodynamics. The average efficiency of energy transfer from herbivores to carnivores is
