Consider a stoppered flask containing benzene, iodine, and air which has reached equilibrium at 298 K. Which one of the following statements concerning the system at equilibrium is true? The pressure of the vapour phase is not constant. Evaporation of the liquid continues. The colour of the liquid phase will change. The mass of solid iodine is not constant. Question Solutions of A and B are mixed and brought to equilibrium. The starting concentrations of A and B are 0.80 mol/L, each. C and D are produced according to the following equation: A(aq) + B(aq) F C(aq) + 2D(aq) If the equilibrium concentration of C is 0.60 mol/L, the equilibrium concentration of A is:
