Answer to Question #279970 in Inorganic Chemistry for Gina

Question

For the reaction H2(g) + l2(g) = 2 HI(g), equilibrium concentrations at 25°C are [H2] = 0.0510 mol/L, [ I2] = 0. 174 mol/ L, and [ HI ] = 0.507 mol/L.

What is the value of k at 25°C?

Answer 1

Reaction is

H2 + I2 $\iff$ 2HI

Equilibrium constant Kc = [C]^c[D]^d/[A]^a[B]^b

a=1

b=1

c=2

Constant = (0.507)²/0.0510×0.174

Answer=29.486888292
