Question

1 pts D Question 4 The reaction shown is at equilibrium. If a student adds more X to the system, what happens Immediately (at that Instant) to Q and K? X+ YZ Both decrease Both increase OQ gets larger and K gets smaller. Ok gets larger and gets smaller. Kremains constant and increases Okremains constant and Q decreases.

Answer 1

as con efficients of Fon reaction, the reaction quotent, a the nato of of Concentrations Products of oven those neactants taking stoichiometric every neagents the exponent of Concentrations. for the reaction X+ Yz, ef Concentrations Xr, z stage [x], [y] and [z] respectively, then [x] [v Hence, of at a be Constant, k reaction quotent Equilibrium equilibrium at cauilibrium : K arie [ zeg EzJea, [xJeg, [rea equilibrium Concentrations of Z x and [x] eq [Y] ea respectively. ony If Concentrations reactant Product is chan ged, then reaction quotient, a charges but equilibrium Constant, K is Constant at Porticular temperature. If Concentration any changes, then the system such KeeP equilibrium Constant, K Same. reagent way as to reacts As hence and [x is increases added, mone but remains immediately K decreases [z [x][r Constant. Hence, the last option is Connect. K remains Constant and Q decreases.
