A solution is prepared such that the initial concentration of Cd2+ is 3.80×10-2 M and the initial concentration of Br is 7.50x10-2 M. Cd2+ and Br are allowed to react as shown below to establish equilibrium with the complex CdBr42-. equilibrium concentration of the complex CdBr42- is determined to be 2.9×10-3 M. Cd2* (aq) + 4 Br (aq) = CdBr42- (aq) %3D What is the formation constant, Kf, for this complex?

At room temperature when HI (aq) is added to potassium bisulfite, KHSO3(s), sulfur dioxide is formed and the reaction vessel becomes cold.  HI (aq) + KHSO3(s)→ SO2(g) + H2O(l) + K+(aq) + I-(aq). A.)Once the process has reached equilibrium at room temperature, which of the following must be true? choose one....(ΔH<TΔS, ΔH=TΔS, ΔH>TΔS, or need more info). B.) Once the process has reached equilibrium at room temperature, which of the following must be true? choose one....(ΔSuniv<0, ΔSuniv=0, ΔSuniv>0, or need more info).

Consider the general reaction below. 2A(g) + B₂(g) = 2AB(g) K = 6.4 x 10-6 @ 298 K The reaction was initiated by combining 0.70 mol A and 0.90 mol B2 in a 2.0 L container. Calculate the equilibrium concentrations of the components. What is the equilibrium concentration of AB? 10[? ] [AB] = [?] x 10¹ M
