Question
2HI (g) H_2(g) I_2(g) The above reaction is at equilibrium in a 4.2 liter vessel with a compressible lid. I place a 380 pound gorilla on the lid of this reaction vessel, decreasing the volume. The gorilla is angry. Choose the best overall answer: Kc goes down KC goes up The reaction proceeds "to the left, " generating more reactant The reaction proceeds "to the right, " generating more product There is no net shift, the reaction remains at equilibrium The Gorilla eats the reaction vessel, making the whole question moot.Explanation / Answer
According to the Le-Charterlier's principle,
If the pressure is increased, reaction will takes place in a direction which will bring about lowering f pressure. This implies that the equilibrium will shifts in the direction which produces the smaller no. of gas molecules.
But her the number of moles will remain the same & We are decreasing the volume of the container so the pressure of the complete reaction increasing, so there is no net shift, the reaction remains at equilibrium.
