Question

How many grams can be prepared until equilibrium is attained? carbon disulfide is prepared by heating sulfur and charcoal. the chemical equation is:?

Answer 1

Kc = [CS2] / [S2][C] but, since C is solid, it doesn't fit here 
Kc = [CS2] / [S2] 
S2(g) + C(s) ---> CS2(g) 
13.8mole S2 / 6.05L = 2.28M 

Kc = x / 2.28-x 
9.4 x (2.28-x) = x 
21.43 - 9.4x = x 
21.42 = 10.4x 
x = 2.05M = [CS2] 
2.05M x 6.05L = 12.46moles 
12.46moles x 76gmole = 946.96g CS2
