How does the entropy change in the reaction 2c3h6g 9o2g 6co2g 6h2og?

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.


Is the change in entropy, delta S, positive or negative for a spontaneous reaction?

For a spontaneous reaction, the change in entropy (delta S) is typically positive.

How does the entropy change in the reaction 2C3H6g 9O2g 6CO2g 6 H2Og?

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.


What can be said about an exothermic reaction with a negative entropy change?

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.
