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.

Entropy can decrease in a reaction when a system transitions from a more disordered state to a more ordered state, often observed in processes like crystallization or the formation of complex molecules from simpler ones. This decrease typically occurs in a local context, as the overall entropy of the universe still tends to increase according to the second law of thermodynamics. Additionally, external energy input can drive reactions that lead to a decrease in entropy within a system. However, it’s important to remember that while entropy may decrease locally, the total entropy of the combined system and surroundings will 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.
