Which phase change represents a decrease in entropy?
In respect to this, which reaction would cause a decrease in entropy?
In an exothermic reaction, the external entropy (entropy of the surroundings) increases. In an endothermic reaction, the external entropy (entropy of the surroundings) decreases.
Secondly, which sample has lowest entropy? Solids have the fewest microstates and thus the lowest entropy.
Likewise, is condensation a decrease in entropy?
A phase change from a liquid to a solid (i.e. freezing), or from a gas to a liquid (i.e. condensation) results in an decrease in the disorder of the substance, and a decrease in the entropy.
When ice melts Does entropy increase or decrease?
At the higher temperature, the reaction is not feasible as the entropy of the reaction is decreasing. However, ice will melt at this temperature, as the entropy increases : Both the processes of ice melting at 10oC and water freezing at -10oC are spontaneous reactions; they can occur.
