Salut Namur123,
2 BrCl ⇌ Br2 + Cl2
-------------------------------------------------------------------------------------
cGG (0,060 - 2x)mol/L x mol/L x mol/L
0,0085 = x mol * x mol / (0,060 mol - 2x mol)2 I √
0,0921 = x / 0,060 - 2x I * (0,060 - 2x)
0,0921 * (0,060 - 2x) = x
0,005531 - 0,1842x = x
0,005531 = 1,1842x
x = 0,00467 mol/L
Welche Konzentrationen stellen sich ein ?
cGG (Br2) = cGG(Cl2) = 0,00467 mol/L
cGG (BrCl) = 0,060 - 2 * 0,00467 mol/L = 0,05066 mol/L
Kc(150°) = Kp(150°)
Bonne chance :)
