in fhe process of dissolving salt in water, the entropy increases . This means that the sign of delta S is .........(positive , negative) and that randomness of the system -------(increases, decreaes , stays same).
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)
As a result of any natural process, the total entropy of any large system plus that of its environment A) never decreases. B) sometimes decreases. C) never increases. D) always stays the same
5) As a result of any natural process, the total entropy of any large system plus that of its environment A) never decreases. B) sometimes decreases. C) never increases. D) always stays the same.
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
An ideal gas is compressed and cooled. For this process the entropy of the gas a. Increases b. Decreases c. Stays the same d. Cannot be determined from the information given Thermodynamics
Indicate whether the entropy of the system increases or decreases for each of the following processes. Include a BRIEF explanation. Make up a process for (d) and indicate if the entropy of the system increases or decreases in that process, and provide a brief explanation as well. a) Water boiling at 100.0°C b) 2H2(g) + O2(g) ---> 2H2O(g) c) liquid water freezes at 0.0°C d) e) water vapor expanding from 1.0L of volume to 2.0L of volume f) mixing 10mL...
6) When a spontaneou s, endothermic reaction occurs at constant temperature and pressure, the entropy change of the surroundings is: a) impossible to tell b) positive c) negative d) zero a) ΔG > 0 One finds that the equilibrium constant for a particular reaction increases with increasing temperature. Assuming that the standard reaction enthalpy and entropy are temperature independent, this means that: a) The standard reaction enthalpy is less than zero 8) b) The standard reaction entropy is greater than...
Entropy (S) The second factor involved in determining whether or not a process is spontaneous is the change in randomness or entropy (AS). Entropy is represented by the symbol S. Again, experience can help us understand the relationship between entropy and spontaneous processes. If we look at the two drawings below, we can predict which picture represents the stack of marbles "before" and after they are bumped. We expect the stack of marbles (less random, lower entropy) to be the...
7-During a heat transfer process, the entropy of a system Never decreases Always increases - Always decreases Correct answer is indicated with the red square, please explain how to arrive to that answer - Sometimes decreases
