Answer:
the correct answer is E
Explanation:
None of the options is correct, because entropy is the thermodynamic magnitude that indicates the degree of molecular disorder of a system, in exothermic processes energy or heat is released to the medium and energy is taken from the medium in endothermic processes, entropy if it depends of the temperature since the temperature is what sometimes determines if the process is spontaneous or not, and the delta universe in spontaneous processes is not always greater than zero, it is more frequently less than zero with negative values.

Answer:
The answer to your question is 40 L of NH₃
Explanation:
Data
Volume of NH₃ = x
mass of N₂ = 25 g
mass of H₂ = excess
Balanced chemical reaction
N₂ + 3H₂ ⇒ 2NH₃
Process
1.- Find the molar mass of N₂ and NH₃
N₂ = 14 x 2 = 28g
2NH₃ = 2[ 14 + 3] = 34 g
2.- Write a proportion to solve this problem
28 g of N₂ --------------- 34 g of NH₃
25 g of N₂ ------------- x
x = (25 x 34)/28
x = 30.36 g of NH₃
3.- Calculate the volume of NH₃
17 g of NH₃ -------------- 22.4 L
30.36 g of NH₃ -------- x
x = (30.36 x 22.4) / 17
x = 40 L
