At a certain temperature, this reaction establishes an equilibrium with the given equilibrium constant, Kc.  
3A(g) + 2B(g) <------> 4C(g)  
Kc= 3.13x 10^31

If, at this temperature, 1.90 mol of A and 4.00 mol of B are placed in a 1.00-L container, what are the concentrations of A, B, and C at equilibrium?

Solutions

Expert Solution

                         

Initial                  1.90              4                 0

Final                  (1.90-3x)        2x              4x

solve for x, it will be close to 0.63

Hence the final concentration will be

C = 4 * 0.6328 = 2.5312 moles

B = 4 - 2 * 0.6328 = 2.73 moles

A = 1.90 - 3 * 0.6328 = 0.0016 moles
