CH4(g) + H2O(g) CO(g) + 3H2(g)
The products becoming more spread out.
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder. However, if both the reactants and products are in the same state, the change in entropy may be minimal.
If there is an increase in the number of gas molecules, then S > 0.
The entropy increases as there are more molecules on the product side compared to the reactant side. This increase in randomness and disorder leads to a positive change in entropy for the reaction.
At high temperature the entropy increase.

The entropy increase in this reaction.
The products becoming more spread out.
The increase in entropy will depend on the physical states of the reactants and products. If the reactants are solid and the products are gaseous, there will likely be an increase in entropy due to the increase in disorder. However, if both the reactants and products are in the same state, the change in entropy may be minimal.
A combustion reaction typically results in an increase in entropy due to the increase in the number of gaseous molecules formed during the reaction, leading to more disorder in the system. Therefore, combustion generally has a positive entropy change.
If there is an increase in the number of gas molecules, then S > 0.
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.
The entropy increases as there are more molecules on the product side compared to the reactant side. This increase in randomness and disorder leads to a positive change in entropy for the reaction.
Reactions that increase the moles of gas will increase in entropy.
The entropy change in a reaction can be calculated by comparing the entropy of the products to the entropy of the reactants. Without specific entropy values provided, it is difficult to determine the exact change. However, in general, the entropy change is positive in reactions where the products have higher entropy than the reactants, indicating an increase in disorder.
The reaction N2 (g) + 3H2 (g) → 2NH3 (g) shows an increase in entropy because it involves an increase in the number of gaseous molecules from 2 to 4. Therefore, the entropy change for this reaction is positive.
