What would cause entropy to increase in a reaction?

Answer 1

The products becoming more spread out.

Answer 2

The third law of thermodynamics states that as you tend towards absolute 0, entropy tends towards 0.

This works both ways. As you tend towards higher temperatures, you tend towards a higher entropy.

This is only a brief understanding. To learn more about it in depth there is a good source of info at the related link at the foot of the page.

Answer 3

Entropy is the physical measurement of the statistical probability of disorder. Heat is the energy transfer between systems. In order for heat transfer, atoms or molecules become excited. Since an excited state of jumbling, interacting constituents is more disorderly, any chemical reaction that produces heat will increase the entropy of the universe.

Answer 4

(Explanation): remember entropy=chaos. So, if the products spread out physically, then there is chaos because the location of the products is randomized.

Answer 5

Because the particles have more random movements.

Answer 6

An increase in the number of moles of gas, an increase in temperature, or a change from a more ordered to a more disordered state can cause entropy to increase in a reaction.
