Which of the following reactions would have an increase in entropy?

C(graphite)+H  2 ​O(g)→CO(g)+H  2  (g)

Explanation:

The entropy of a system increases whenever its particles have more freedom of motion.

Thus.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
