Question

Read the following reactions.

Reaction 1: NaCl(s) -> Na+ (aq) + CI-
Reaction 2: N2 + 3H2 -> 2NH3

Which reaction leads to an increase in entropy?

Only Reaction 1
Only Reaction 2
Both Reaction 1 and 2
Neither Reaction 1 nor 2
​

Answer 1

Answer:

Only Reaction 1

Explanation:

In reaction 1, there is a change in state from solid to liquid. Hence, there is an increase in number of ways particles and their energies could be arranged. As a result, entropy increases.

In reaction 2, there is a decrease in amount of gas particles (4 mol to 2 mol). Hence there is a decrease in the number of ways particles and their energies could be arranged. As a result entropy decreases

Answer 2

Only Reaction 1 will lead to an increase in entropy.

What is Entropy?

This is the degree of disorderliness or randomness of a particle and it is

denoted as S.

In states of matter, conversion from solid to other states such as liquid

brings about increase in entropy which is why only reaction 1 experienced

this phenomenon.
