At a certain temperature, the equilibrium constant K for the following reaction

Question

At a certain temperature, the equilibrium constant K for the following reaction is 132.: Use this information to complete the following table. Suppose a 33. L reaction vessel is filled with 1.0 mole of NO. 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. What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits. There will be very little N_2 and O_2. There will be very little NO. Neither of the above is true.

Explanation / Answer

1. Neither of the above is true because K = 132. If K is between 10-3 to 103, then the concentrations of reactants and products are moderate.

2. K = 1/132 = 7.58 x 10-3 since it is backward reaction.

3. K = (132)2 = 1.74 x 102 since the reaction is multiplied by 2.
