Rory Morse · Answer 1

When the balanced equation for the reaction is:

H2 (g) + i2 (g) ⇄ 2Hi

initial 0.5 0.5 X

-X - X + X

Final (0.5-x) (0.5-x) 2X

by substitution at the Kc formula:

Kc = [Hi]^2 / [H2] * [i2]

53.3 = (2X) ^2 / (0.5-X) (0.5-X) by taking the square route

√53.3 = 2X / (0.5-X)

∴X = 0.39 m

∴[Hi] = 0.39 m
