Nb” data yang diketahui berupa persamaan reaksi sehingga untuk menghitung Kp tidak digunakan perbandingan mol, melainkan perbandingan koefisien, anggap saja koefisennya adalah mol…. Ingat fase yg digunakan hanya gas…

7.       At a given temperature, in a container of 10L there is an equilibrium reaction of:
2SO3 (g) Û 2SO2 (g) + O2 (g)
If 80 grams of SO3 (S=32, O=16) is heated and after reaching the equilibrium, the mole ratio of SO3: O2 = 2: 1. Dissociation deqree at that time is ….
                Answer:
Mol SO3 = 80 gram /80 = 1 mol
Misalnya mol SO3 yang bereaksi adalah x mol
2SO3 (g) Û 2SO2 (g) + O2 (g)
M: 1 mol        -               -
B: x mol         x              ½ x
S: 1-x              x             ½ x
Perbandingan SO3 = 2
                           O2      1

1-x = x
2x = 1
X =1/2
Jadi:derajat disosiasi SO3
a = mol terurai = x = ½ = 1/2
       Mol mula2       1     1

Nb: “pelajari materi derajat disosiasi, meski belum sempat miss ajarkan”
Nanti ada soalnya di PG, reaksinya NH4Cl Û NH3 + HCl
