Question
Methane and hydrogen sulfide react to form carbon disulfide and hydrogen, ike this: CH4(g)+ 2H,s(g)-CS2(g) +4H2(g) Suppose a mixture of CH, H,s, Cs, and H, has come to equäbrium table below will cause in the composition of the mixture in the vessel. Also decide whether the equlibriam shifts to the right or le in a closed reaction vessel. Predact what change, if any, the pertrbations in the ft. perturbation change in composition shift in equilibrium O to the right (none) O to the right The presaure of CH wil The pressure of Hs wll ? to the left Some Cs; is added The c ressure of 18 ml! Some CKs is remaved The pressure f 32 wll (none) Oto the right The volume of the vessel The pressure of CH wi The pressure af IHs wb none) nat chenge 1 Don't KnowExplanation / Answer
According to Lechateliers's priciple, when a reaction at equilibrium is subjected to change in concentration, pressure and temperature, the equilibrium tries to oppose it and moves in a direction so as to undo the change.
In this context when CS2 is added (i.e.- increasing product concentration) shifts the equilibrium to right hand side.
In this context when CH4 is removed (i.e.- decreasing reactant concentration) shifts the equilibrium to left hand side.
In the given equilibrium, moles of reactant = 3 mole and moles of product = 5 moles . Thus increasing volume shifts the equilibrium to right hand side.
