Consider the following chemical equilibrium: 2 H2 (g) + O, (g) = 2H,0 (1) Now write an equation below that shows how to calculate K, from K̟ for this reaction at an absolute temperature T. You can assume T is comfortably above room temperature. If you include any common physical constants in your equation be sure you use their standard symbols, found in the ALEKS Calculator. K (RT) K

Consider the following equilibrium reaction: H2CO3 (aq)  ⇌  H+ (aq) + HCO3– (aq);     K = 5.0 x 10–7  If the initial concentrations of the species are: [H2CO3] = 0.100 M;   [H+] = 2.00 x 10–5 M;   [HCO3–] = 2.00 x 10–3 M Which one of the statements below describes the relationship between Q and K and then the correct direction of chemical change?   Select one: a. Q = K, so the reaction is at equilibrium. b. Q > K, so the reaction moves to the right. c. Q < K, so the reaction moves to the right. d. Q < K, so the reaction moves to the left. e. Q > K, so the reaction moves to the left.

Consider the following chemical equilibrium: 2 H2 (g) + 0, (g) =2H,0(1) Now write an equation below that shows how to calculate K, from K, for this reaction at an absolute temperature T.

Consider the decomposition reaction: X(g) + 2 Y(g) XY2(s) where X and Y are some chemical groups. At a certain temperature the equilibrium constant for this reaction is Ke= 0.108. If you start with a large amount of XY2 (s), c= what will be the concentration of Y(g) once the system reaches equilibrium? (HINT: Draw an ICE table or you will likely get this wrong!)

Write the equilibrium-constant expression for the reaction A(s) + 3 B(1) = 2C(aq) + D(aq) in terms of [A], [B], [C] , and [D] , as needed. Note that Ke, which is sometimes symbolized as Keg, denotes that the equilibrium constant is expressed using molar concentrations. For this question, K. means the same thing as Keq. K. =
