A mixture of reactants and products has a equilibrium constant of 4.7 and initially contains 0.035 M H2O, 0.050 M CH4, 0.15 M CO, and 0.20 M H2. In which direction will the reaction go in order to attain equilibrium?

Respuesta :

Answer: Reaction will move in forward direction in order to attain an equilibrium.

Explanation:

  • [tex]K_c>Q_c[/tex]  reaction will move in forward direction.
  • [tex]Q_c>K_c[/tex]  reaction will move in backward direction.
  • [tex]Q_c=K_c[/tex]  reaction is at equilibrium.

[tex]CH_4+H_2O\rightleftharpoons CO+3H_2[/tex]

[tex]K_{c}=4.7[/tex]

[tex][H_2O]=0.035 M,[CH_4]=0.050 M,[CO]=0.15 M,[H_2]=0.20 M[/tex]

The expression for equilibrium quotient is written as :

[tex]Q_{c}=\frac{[CO][H_2]^3}{[H_2O][CH_4]}=\frac{0.15\times (0.20)^3}{0.035\times 0.050}=0.6857[/tex]

Since, [tex]K_c>Q_c[/tex] reaction will move in forward direction.
