What reactions would have a decrease in entropy?
2NO2(g) N2O4(g)
Reactions would result in decreased entropy?
Water Freezing
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
What phase has the lowest entropy?
Solid to liquid
Under what condition can entropy decrease in a system?
First of all, entropy is the defined as the extent to which something is disordered. In chemistry, for entropy in a SYSTEM to decrease, the products of a reaction must be less disordered than the reactants. The extent of "disordered-ness" can be seen by the physical states of the substances. A gas is more disordered than a liquid, which is more disordered than a solid. So, an example of a reaction that leads to a decrease in entropy is: HCl(gas) +NH3(gas) -----> NH4Cl(solid) So you see, there are more gaseous molecules in the reactant side of the equation than in the product side, which means the products are less disordered than the reactants. ----------------------------------------------- However, one must note that if the entropy of a system(reaction) decreases, the entropy of the surroundings should increase. This is because change in TOTAL entropy(A) = change in entropy of SYSTEM(B) + change in entropy of SURROUNDINGS(C). It is a rule that A must increase in every case ( have a positive value). If the B is negative(a decrease in entropy), C must be positive(an increase in entropy) to keep the value of A positive.
What the would result in a decrease in entropy?
The meaning is more order.
What result in a decrease in entropy?

How can you decrease the entropy of static body?
You can decrease the entropy of a static body by reducing the temperature.
What would result in decreased entropy?
Water Freezing
Is there anyway to decrease the entropy?
Only by increasing the entropy of another system.
What reactions would have a decrease in entropy?
2NO2(g) N2O4(g)
Reactions would result in decreased entropy?

Does diffusion involve a decrease in entropy?
no.
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
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 results in decrease in entropy?
