Macmillan Learning 2 NO(g) + O2(g) = 2 NO2(g) Write the equilibrium-constant expression for the reaction shown in terms of [NO], [O, ], and [NO,]. Kc, which is sometimes symbolized as K or Keq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, K, means the same thing as K and Keq. K =

Write the equilibrium constant expression, K , for the following reaction: (If either the numerator or denominator is blank, please enter 1.)   K=

Coal can be used to generate hydrogen gas (a potential fuel) by the following endothemic reaction (heat is on the reactant side of the equation). C (3) + H20 (g) = co (g) + H2 (g) If this reaction mixture is at equilibrium, predict whether each of the following will resuit in the formation of additional hydrogen gas, the formation of less hydrogen gas, or have no effect on the quantity of hydrogen gas. Part A adding more C to the reaction mixture the formation of additional hydrogen gas the formation of less hydrogen gas O no effect on the quantity of hydrogen gas

Consider the equilibrium system described by the chemical reaction below. Determine the concentration of O, at equilibrium by writing the equilibrium constant expression and solving it. Complete Parts 1-2 before submitting your answer. = 2 H₂O(g) 2 H2(g) + O̟₂(g) 1 2 NEXT At this temperature, the Kc = 2.4 × 103 and the equilibrium concentrations of H2O and H2 are 0.11 M and 0.019 M, respectively. If [x] represents the equilibrium concentration of O2, set up the equilibrium expression for Kc to solve for the concentration. Each reaction participant must be represented by one tile. Do not combine terms. Кс = 2' = 2.4 × 103 > RESET [0.11] [0.019] 2[0.11] 2[0.019] [0.11]² [0.019]² [x] [x]² [2x] [2x]²

At a certain temperature, the equilibrium constant K for the following reaction is 3.1 × 10 : H,(g) + I,(g) = 2 HI(g) Use this information to complete the following table. Suppose a 36. L reaction vessel is filled with 1.7 mol of HI. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little H2 and I2. There will be very little HI. Neither of the above is true. What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. K = 1 2 HI(g) H2(9)+I,(9) What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. K = I 2 H,(9)+21½(9) 4 HI(g)

Write the equilibrium-constant expression for the reaction shown in terms of [SO2], [CO2], [CS2], and [O2]. 2SO2(g)+CO2(g)↽−−⇀CS2(g)+3O2(g) ?c, which is sometimes symbolized as ? or ?eq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, ?c means the same thing as ? and ?eq.
