At 460 °C, the reaction: SO2(g) + NO2(g) ↔ NO (g) + SO3(g) has Kc = 85.0. Suppose 0.180 mol of SO2, 0.180 mol of NO2, 3.00 mol of NO and 3.00 mol of SO3 are placed in a 2.0 L container at this temperature. What will the concentrations of all the gases be when the system reaches equilibrium?

Nitrosyl bromide decomposes according to the equation given below. If 0.640 mole of NOBr is placed in a 1.00 L flask containing no NO or Br2 it is found that at equilibrium there is 0.460 mole of NOBr.  What is the value of Kc for this reaction?                                                                   2 NOBr (g)     →     2 NO (g)     +     Br2 (g)   1.38 x 10−2 7.26 7.12 x 10−3 3.52 x 10−2 28.4

Calculate the equilibrium concentrations for all reactants and products if initial concentrations of CH4 is 0.400 M, H2S is 0.800 M, CS2 is 0.400 M, H2 is 0.800 M are mixed and allowed to establish equilibrium.  The Kc for the reaction is 0.0360 and the equilibrium concentration of CH4is 0.556 M.   CH4(g) + 2H2S(g) ↔  CS2(g) + 4H2(g) Group of answer choices [CH4] = 0.556 M, [H2S] = 0.488 M, [CS2] = 0.556 M, [H2] = 1.42 M. [CH4] = 0.556 M, [H2S] = 1.11 M, [CS2] = 0.244 M, [H2] = 0.176 M. [CH4] = 0.556 M, [H2S] = 0.244 M, [CS2] = 0.956 M, [H2] = 1.36 M. [CH4] = 0.556 M, [H2S] = 1.11 M, [CS2] = 0.556 M, [H2] = 1.42 M.

At a certain temperature, the equilibrium constant K for the following reaction is 0.0017: CO(g)+ H₂O(g) CO₂(g) + H₂(g) Use this information to complete the following table. Suppose a 27. L reaction vessel is filled with 1.5 mol of CO and 1.5 mol of H₂0. What can you say about the composition of the mixture in the vessel at equilibrium? What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. CO,(9)+H,(9) CO(g)+H,O(g) What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. 2 CO(g) + 2H₂O(g) 2 CO₂(g)+2H₂(9) There will be very little CO and H₂O. There will be very little CO₂ and H₂. Neither of the above is true. K = 0
