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.
Synthesis reactions such as dehydration synthesis. For a reaction to proceed the there must be a net decrease in the Gibbs Free Energy of the system. The Gibbs Free Energy is made up of two terms: Enthalpy or Heat Content H Entropy S For a reaction in which the entropy is increasing to proceed there would have to be a sufficient release of heat content (enthalpy) such that Change in Free Energy G would be negative, ie decrease...
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.

When energy is transformed, entropy can either increase or decrease. For example, in many energy transformations, such as combustion or chemical reactions, entropy tends to increase due to the dispersal of energy. However, in some processes, such as certain phase changes, entropy can decrease.

The meaning is more order.
Reactions involving gases can affect the entropy of a system by changing the number of gas molecules before and after the reaction.

Conversely, a decrease in the number of gas molecules usually results in a decrease in entropy.
To decrease the entropy of a static body, you would need to decrease the disorder or randomness of its particles. This can be achieved by cooling the body, which can lower the thermal motion of its particles and reduce their entropy. Other methods include applying pressure to order the particles or removing impurities that contribute to disorder.
A gas typically increases the entropy much more than the increase in moles.
There is at least one non spontaneous reactions occuring in the particular system. So someone or something has to shred energy in order to continue the procedure.
