5.2.3 Entropy

Question 1

Define entropy.

Answer 1

The entropy of a system is a measure of the disorder (chaos) in it. The more entropy it has, the more disordered it is.

Question 2

Which one is the most disordered, gas, liquid or solid?

Answer 2

Gas.

Question 3

What would happen to the entropy if the reactant is a solid but the products are gases?

Answer 3

There is an increase in disorder and therefore an increase in entropy.

Question 4

Can entropy reactions be feasible?

Answer 4

Yes.
