Answer #1

molarity of I2 = no of moles/volume in L

= 3.76/4 = 0.94M

molarity of Cl2 = no of moles/volume in L

= 3.76/4 = 0.94M

---------- 2ICl(g) --------------> I2(g) + Cl2(g)

I---------- 0 --------------------0.94----------0.94

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

E-------- 2x ------------------0.94-x ------ 0.94-x

Kc = [I2][Cl2]/[ICl]^2

0.11 = (0.94-x)(0.94-x)/(2x)^2

0.11 = (0.94-x/2x)^2

0.3316 = 0.94-x/2x

0.3316(2x) = 0.94-x

x = 0.565

[Cl2] = 0.94-x = 0.94-0.565 = 0.375M
