Entropy value

[IreneSeo3F]

What does the entropy value tell us? Is the numerical value significant or do we only focus on the sign?

[Jack_Pearce_2H]

Usually check the sign first. If it is>0 then it is spontaneous and if it is <0 it is non-spontaneous. From there the larger the abs value of the number is directly related to the more spontaneous or non spontaneous the reaction is relative to its original sign.

[Mackenzie Van Val 3E]

Entropy is the measure of how disordered a system is. The numerical value is significant; a larger negative value will mean a greater change in entropy than a smaller negative value, as will a larger positive entropy than a smaller positive one. At equilibrium, the total entropy of a reaction will be equal to zero, which is also important to note.

Entropy tells us how many microstates a system can access

[Neel Sharma 3F]

The sign is often easier to understand. Positive means disorder increases and negative means it has become more orderly. The number is often useful when dealing with the positional entropy value.

[Aria Movassaghi 1A]

Sign is probably more important in most cases, - meaning non-spontaneous, + spontaneous

The entropy value measures the disorder of the system. Normally, if S is positive, entropy is increasing while the opposite can be said when S is negative.

[Sera Aintablian 2E]

A positive entropy value corresponds to spontaneity, and a negative entropy value corresponds to a nonspontaneous reaction.
The greater the entropy, the more disorder in the system.
When considering molecules, the greater the molecular complexity, the greater the molar entropy value.

Entropy measures the disorder in a system. A positive change in entropy is usually associated with a spontaneous process, while a negative change in entropy is usually associated with a non-spontaneous one.

[Halle Villalobos 3E]

Hi! Entropy is the measure of disorder in a system. A positive entropy corresponds to spontaneity, whereas a negtaive value is linked to a nonspontaneous reaction. I hope this helps!

[SahajDole_1C]

It tells us how disordered the system is

[Lesly Lopez 3A]

The entropy value measures the disorder of the system. Usually, if S is positive then that means that entropy is increasing. When S is negative it is more likely that the entropy id decreasing.

[Sabine Salvucci 2E]

Hello! Entropy is a measure of the disorder of a system. If the change in entropy (delta S) is positive, entropy is increasing and the process is spontaneous. If delta S is negative, entropy is decreasing and the process is non-spontaneous.

[Kareena Patel 1G]

I would just worry about the sign of entropy. Positive entropy is more disorder/spontaneity and negative entropy is less disorder/nonspontaneity.

[Lesly Lopez 3A]

The sign can tell you the most important thing. In most cases negative meaning non-spontaneous while positive means the reaction is spontaneous.

[Kyla Roche 2K]

Essentially the entropy tells us the disorder and entropy increases with a larger volume, a larger atom due to more electrons, and the gas phase has the largest entropy because there are the most possible states in this phase.

[Jason Knight - 1F]

The entropy value can be thought of as a measure of disorder of the system. A positive value tells us the reaction is spontaneous, where a negative value tells us the reaction is non-spontaneous, or not favorable.

[Jacob Schwarz-Discussion 3I]

Entropy tells us how much disorder there is in a system. When the volume increases, the entropy increases. When entropy is positive, the process is spontaneous.
