It increases; more freely moving particles.
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.
It increases
CH4(g) + H2O(g) CO(g) + 3H2(g)
At high temperature the entropy increase.
To determine the final entropy change for a reaction when multiplied by a choice, you would typically apply the principle of additivity of entropy. If you multiply a reaction by a factor, the change in entropy for the overall reaction will also be multiplied by that same factor. Therefore, if you have the standard entropy change for the original reaction, you would multiply that value by the factor you used to scale the reaction to find the final entropy change for the intermediate.
At high temperature the entropy increase.
The entropy change (ΔS) for this reaction would typically be negative, as gases have higher entropy than solids. This indicates a decrease in disorder or randomness, which is expected when gases combine to form a solid.
In the reaction 2O₃ → 3O₂, the entropy increases. This is because two molecules of ozone (O₃) decompose into three molecules of oxygen (O₂), resulting in an increase in the number of gas molecules. Since entropy is a measure of disorder or the number of ways to arrange particles, the formation of more gas molecules leads to greater disorder, thus increasing the overall entropy of the system.
To calculate the standard entropy change (ΔS°) for a reaction, you need to use the formula: [ \Delta S° = \sum S°{\text{products}} - \sum S°{\text{reactants}} ] You would sum the standard entropy values of the products and subtract the sum of the standard entropy values of the reactants. If you provide the specific reaction and the standard entropy values, I can calculate it for you.
The products becoming more spread out.

The entropy INCREASES. There are more moles in the products than in the reactants.
