What happens to the entropy in the reaction?
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
What must happen to the entropy of the universe during a spontaneous reaction or process?
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
The favorability or spontaneity of a reaction increases when during the course of a reaction?
The favorability or spontaneity of a reaction increases when the overall entropy of the system increases, or when the free energy of the system decreases. This can happen when reactants are in a more disordered state, when the system achieves greater stability, or when the reaction releases heat.
When water becomes ice the entropy decreases does this contradict the second law?
No, the decrease in entropy of water turning into ice does not violate the second law of thermodynamics. The second law states that the total entropy of an isolated system can never decrease, but entropy can decrease locally within the system as long as there is a corresponding increase in entropy elsewhere. In the case of water turning into ice, the decrease in entropy of the water molecules is offset by an increase in entropy in the surroundings.
Does diffusion involve a decrease in entropy?
no.
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants

What reaction would cause decrease in entropy?
CO(g)+3H2(g)->CH4(g)+H2O(g)
What would happen to the entropy in the reaction 2O3 g 3O2 g?
It increases
What types of reaction would decrease the entropy within a cell?
Complex reactions where small molecules are converted into larger, more ordered structures, such as polymerization or crystallization, can decrease entropy within a cell. These reactions reduce the randomness and disorder of molecules, leading to a more ordered state and a decrease in entropy.
What does the entropy of a reaction describe?
The amount of randomness in the system
How does an endothermic reaction change the entropy of the surroundings?
An endothermic reaction which absorbs heat from the surroundings decreases the entropy of the surroundings. This is because the surroundings lose thermal energy during the reaction, leading to a decrease in the disorder or randomness of the surroundings.
What must happen to the entropy of the universe during a spontaneous reaction or process?
The entropy of the universe must increase during a spontaneous reaction or process. This is in accordance with the Second Law of Thermodynamics, which states that the total entropy of an isolated system can never decrease over time.
Under what condition can entropy decrease in a system?
Entropy can decrease in a system if energy is removed or transferred elsewhere, causing a decrease in randomness or disorder within the system. This could occur, for example, if the system undergoes a phase transition where the molecules become more ordered or structured.
What reactions would have a decrease in entropy?
2NO2(g) N2O4(g)
How do reaction involving gases affect the entropy of a system?
Reactions involving gases can affect the entropy of a system by changing the number of gas molecules before and after the reaction. An increase in the number of gas molecules typically leads to an increase in entropy, as gases have greater disorder and freedom of movement compared to solids or liquids. Conversely, a decrease in the number of gas molecules usually results in a decrease in entropy.
What describes the entropy change of gas reaction?
if there is an increase in the number of gas molecules , then ^S > 0
