          Question 5

          Marks: 1

          A compound, WX, will dissociate into an X ion and a W+ ion in solution. This is represented by the equation below.  

          WX (aq) X (aq) + W+ (aq)

          2.0 dm3 of a 0.4 mol dm-3 solution of WX was heated to a constant temperature until equilibrium was established. The equilibrium mixture is found to contain 0.1 mol of the W+ ion.  

          What is the correct value of Kc?

          • 0.0143

          • 140

          • 0.00714
