Answer:
Explanation:
To calculate the reduced mass of nitrogen molecule = Mn x Mn/ Mn + Mn
Mn = atomic mass of Nitrogen = 14.00
reduced mass = 14 x 14 /14 + 14 = 7
Similarly for HCl; reduced mass for a hydrogen chloride molecule = Mh x Mcl/Mh + Mcl
where Mh = atomic mass of hydrogen = 1.008
Mcl = atomic mass of chrorine = 34.97
reduced mass for HCl = 1.008 x 34.97 /1.008 + 34.97
= 0.97
There are two equations of Gibb's free energy, ΔG°:
ΔG° = ΔH° - TΔS°
ΔG° = -RTlnK
Let's use the first equation. Since ΔS° is negligible, it is equal to 0. Therefore, ΔG° = ΔH° = 7.11 kJ/mol. We use this value to the second equation.
7.11 kJ/mol = -(8.314 J/mol·K)*(1 kJ/1000 J)*(25 + 273 K)*(lnK)
lnK = -2.8697
K = 0.05671
Therefore, the equilibrium constant is equal to 0.05671.
