Question

O KINETICS AND EQUILIBRIUM Using the general properties of equilibrium constants At a certain temperature, the equilibrium constant K for the following reaction is 0.92: Br (8) + OCI,(g) BIOCI(g) + BrCI(g) Use this information to complete the following table, Suppose a 6.0 L reaction vessel is filled with 1.3 mol of Bry and 1.3 mol of Clz. What can you say about the composition of the mixture in the vessel at equilibrium? There will be very little Br2 and Odlz. There will be very little Broci and Brci. 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 = 0 BrOCK(0)+B+C ) - Br2(0)+OC12(0) What is the equilibrium constant for the following reaction? Be sure your answer has the correct number of significant digits.
