Which relationship or statement best describes delta s for the following reaction:

2h2s(g) + 3o2(g) --> 2h2o(g)

a) delta s = 0
b) delta s < 0
c) delta s> 0
d) delta s = delta h |t
e) more information is needed to make a reasonable prediction.

b) Delta S < 0

Explanation:

The change in the entropy (ΔS) is related to the change in the number of gaseous moles of the reaction: Δn(g) = n(g, products) - n(g, reactants).

Let's consider the following equation.

2 H₂S(g) + 3 O₂(g) → 2 H₂O(g)

Δn(g) = 2 - 5 = - 3. Since Δn(g) < 0, the entropy decreases and ΔS < 0.
