The amount of randomness in the system
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.
At high temperature the entropy increase.
The entropy increase in this reaction.
In this case the entropy increase.
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.
The amount of randomness in the system
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help

The entropy increase in this reaction.
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
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 entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
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.
For a spontaneous reaction, the change in entropy (delta S) is typically positive.
In this case the entropy increase.
An exothermic reaction with a negative entropy change indicates that the reaction releases heat to its surroundings and results in a decrease in disorder or randomness of the system.
