Explanation:

Of phases, from biggest to least entropy is gas>liquid>solid. Dissolve a salt right into solution is boost in entropy due to the fact that the salt has greater space to move. The only decrease in entropy is condensation of water on glass (gas to liquid)


Explanation:

Entropy because that phases are Gas>Liquid>Solid. A salt dissolving into solution has a hopeful entropy change (the equipment becomes much more chaotic). Therefore every one of the noted reactions are a positive readjust in entropy, making E the correct answer.

You are watching: Which of the following describes the entropy changes in gas reactions


Explanation:

Entropy can be assumed of together the tendency for a system to end up being disordered, or random. Osmosis, melting ice, and also a clean room becoming dirty space all examples of entropy in ~ work. Each of these procedures will occur spontaneously there is no the intake of outside energy or work.

If you do a skyscraper, you room incorporating a collection of compounds and building assets into a single, distinct formation. Think of the this way: what room the odds that mommy nature would certainly spontaneously construct a building? This process is very ordered, which method that entropy that the universe has actually decreased.

Example concern #10 : Entropy


Which reaction will result in a an adverse entropy?


Possible Answers:
Correct answer:


Explanation:

A reaction will have a positive change in entropy as soon as the disorder of the device is increasing. This can happen when a liquid transitions to a gas, or an ext gas molecules are developed in the reaction.

Since 2 molecules of gas nitrogen dioxide can integrate to form one molecule of dinitrogen tetroxide, the amount of gaseous molecules is halved. This increases order, i beg your pardon decreases the entropy of the system.
