The change in entropy is related to the change in the number of moles of gas molecules. Determine the change in moles of gas for each of the reactions and decide if the entropy increases decreases or has little to no change.

The given question is incomplete. The complete question is:

The change in entropy is related to the change in the number of moles of gas molecules. Determine the change in moles of gas for each of the reactions and decide if the entropy increases decreases or has little to no change:

A.

B.

C.

D.

A. : decreases

B. : decreases

C. : no change

D. : increases

Explanation:

Entropy is defined as the randomness of the system.

Entropy is said to increase when the randomness of the system increase, is said to decrease when the randomness of the system decrease and is said to have no change when the randomness remains same.

In reaction , as gaseous reactant is changed to solid product, entropy decreases.

In reaction , as 4 moles of gaseous reactants is changed to 2 moles of gaseous product, entropy decreases.

In reaction , as 3 moles of gaseous reactants is changed to 3 moles of gaseous product, entropy has no change.

In reaction   , as 1 mole of gaseous reactant is changed to 3 moles of gaseous product, entropy increases.

the answer is true.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
