Chemistry 102: Equilibrium: Calculate value of equilibrium constant Kp

Question

At 2000 K the partial pressures of an equilibrium mixture of H₂S, H₂, and S are 0.0353 , 0.0351 , and 0.0251  atm, respectively. Calculate the value of the equilibrium constant K_p at 2000 K.

H2​S(g)H2​(g)+S(g)

Answer 1

H₂S(g) <==> H₂(g) + S(g) ... balanced equation

Kp = (H₂)(S) / (H²S)

Kp = (0.0351)(0.0251) / (0.0353)

Kp = 0.0250
