The correct equilibrium mixture reaction quotient (Qc) should be solved and understand given the each graphical images (i-iii).
Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved when the concentrations of reactants and products become constant.
Equilibrium mixture: Some of the reactants an products are present in respective concentrations which have no further tendency to change with time. Generally this process results when the forward reaction proceeds at the same rate as the reverse reactions.
Reaction quotient: This type of chemical equilibrium reaction proceeds likely to produced, given either the pressure (or) the concentration of the reactants and the products. The value can be compared to the equilibrium constant, to determine the direction of the reaction that is take place. Then reaction quotient (Qc) the indication of Q can be used to determine which direction will shift to reach of chemical equilibrium process.
To find: The equilibrium mixture should be identified given equilibrium graphs (1-3).
