The equilibrium constant value for the reaction below is Kc=2.40×10-6 at a certain temperature.
2 H₂S (g) + CH₄ (g) ⇄ 4 H₂ (g) + CS₂ (g) Kc=2.40×10-6
A container is fill with gases until the following concentrations are reached H₂S = 2.200 M, CH₄ = 2.800 M, H₂ = 0.0750 M and CS₂ = 0.0550 M. Calculate the value of the reaction quotient Qc when the concentrations above are reached.
Very large or very small numbers should be entered in scientific notation using the 'E' format, like your calculator. A number like 2.34×10-7 should be entered as 2.34E-7
Qc=Answer
In which direction will the reaction initially proceed? Answer
Kc is reaction constant at exactly equilibrium position.
Qc is a reaction contact at any stage of the chemical reaction.
If Qc < Kc the reaction proceed in forward direction.
If Qc > Kc the reaction proceed in backward direction.
If Qc = Kc the reaction is at equilibrium.
