Tolong no 14 ya ka....

Semoga membantu yaa

n NO2 awal = 4 mol
n O2 terbentuk = 1 mol
V = 1 L

..... 2 NO2 => 2 NO + O2
M 4 mol .............................
R - 2 mol ... + 2 mol . + 1 mol
S .. 2 mol ...... 2 mol .. 1 mol

[O2] = n / V = 1 mol / 1 L = 1 M
[NO] = n / V = 2 mol / 1 L = 2 M
[NO2] = n / V = 2 mol / 1 L = 2 M

Kc = [produk] / [reaktan]
= [NO]² [O2] / [NO2]²
= 2² × 1 / 2²
= 1
