For every natural process entropy of universe is increases that means change in entropy of universe is positive .
For a process to be spontaneous: a) b) the entropy of universe increases and Gibbs energy of the system decreases. the entropy of system decreases and Gibbs energy of the universe increases. the entropy of system increases and Gibbs energy of the universe decreases the entropy of universe decreases and Gibbs energy of the system increases. c) d)
Why is entropy of the universe equal to zero in a reversible process?
why are the other options wrong? For a process to be spontaneous: the entropy of universe increases and Gibbs energy of the system decreases. a) the entropy of system decreases and Gibbs energy of the b) universe increases. the entropy of system increases and Gibbs energy of the universe decreases. c) of universe decreases and Gibbs energy of the d) the entropy increases system

1. For any process the change in entropy of the universe equals the sum of the entropy changes for the system and for the___ 2. Does the formation of complex molecules such as proteins and nucleic acids from more simple molecules contradict the second law of thermodynamics? Yes or no. Explain your answer.

Qualitative Predictions about Entropy Another way of looking at entropy is that the universe is moving toward a broader distribution of energy. The universe has a constant amount of energy as stated in the first law of thermodynamics. The universe started with low entropy (concentrated in the moment before the "big bang") and the entropy has since been constantly increasing by distributing this energy. Heat distribution from high temperature to low temperature is a another example of this phenomenon. Classify...
The second law of thermodynamics states that for any spontaneous process the entropy of the universe must increase. Explain how this statement (increasing entropy) relates to: lambda G_rxn lambda H_rxn lambda S_rxn For this process under standard conditions.
