a) For reaction 2 A(aq)⇋ B(aq) + C(aq), the G° value is -4.25 kJ/mol at 25°C. The initial concentrations of A(aq), B(aq), and C(aq) are 0.525 M, 0.275 M and 0.185 M, respectively. What will be the concentration of A(aq) when the reaction reaches equilibrium at 25.0°C? b) Given that 0.034 g of CaF2 is soluble in 2.0 L of water, calculate its solubility product, Ks.
Consider the following equilibrium system: 302 (8) s 203(g) At a particular time, the rate of O 2(g) being consumed is 3.0 M/s, while the rate of O 3(g) being formed is 2.0 M/s. Is this system at dynamic equilibrium? O Yes, the rate of the forward reaction is equal to the rate of the reverse reaction. O No, the rate of the forward reaction is greater than the rate of the reverse reaction. O No, the rate of the forward reaction is less than the rate of the reverse reaction.

The progress of the reaction H2(g) + Br2(g) 2 2 HBr(g) can be monitored visually by following changes in the color of the reaction mixture (Br2 is reddish brown, and H2 and HBr are colorless). A gas mixture is prepared at 700 K, in which 0.40 atm is the initial partial pressure of both H2 and Br, and 0.90 atm is the initial partial pressure of HBr. The color of this mixture then fades as the reaction progresses toward equilibrium. Give a condition that must be satisfied by the equilibrium constant K (for example, it must be greater than or smaller than a given number).
