For which of the following processes would you expect there to be an increase in entropy? ag+(aq) + cl-(aq) agcl(s) h2o(g) h2o(l) cabr2(s) ca+2(aq) + 2br- (aq) co2(g) co2(s) n2(g) + 3f2(g) 2nf3(g)

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

1.

The fast moving ions are converting to solid product, thus the entropy decreases.

2.

The fast moving gas is converting to liquid product, thus the entropy decreases.

3.

The energy is absorbed by the reactants and the solid reactants are converting to fast moving ions, thus the entropy increases.

4.

The fast moving gas is converting to solid product, thus the entropy decreases.

5.

4 moles of gas is converting to 2 moles of gaseous product , thus the entropy decreases.

mark him as !
