Answer 1

Answer #1

molarity of H2S = no of moles/volume in L

= 0.125/0.45 = 0.277moles

---------2H2S(g)----------------> 2H2(g) + S2(g)

I---------- 0.277 -------------------0 ------------0

C-------- -2x ---------------------- 2x ---------- x

E------ 0.277-2x ---------------- 2x ---------- x

Kc = [H2]^2[S2]/[H2S]^2

1.67*10^-7 = (2x)^2*x/(0.277-2x)^2

1.67*10^-7(0.277-2x)^2 = 4x^3

x = 0.00146

[H2S] = 0.277-2x = 0.277-2*0.00146 = 0.27408M

[H2] = 2x = 2*0.00146 = 0.00292M

[S2] = x = 0.00146M
