Question

Temaan tolong bantu yaa plisss :))
makasih sebelumnya

Answer 1

Kc = ([O2] [SO2]^2) / [SO3]^2

perb mol SO3 : SO2 = 4 : 3

0.5 - 2a / 4 = a / 3
1.5 - 6a = 4a
10a = 1.5
a = 0.15

Shg, ketika mol setimbang :

SO3 = 0.5 - 2a = 0.5 - 0.3 = 0.2
SO2 = 2a = 0.3
O2 = 0.15

Nah karena V = 1, M = n

Kc = ([0.3]^2 [0.15]) / [0.2]^2
Kc = 0.3 × 0.3 × 0.15 / 0.2 × 0.2
Kc = 9/4 × 3/2
Kc = 27/8
