A mixture of 9.22 moles of A, 10.11 moles of B, and 27.83 moles of C is placed in a one-liter container at a certain temperature. The reaction is allowed to reach equilibrium. At equilibrium the number of moles of B is 18.32. Calculate the equilibrium constant for the reaction: A (+ 2B) = 3c ig T 4.23 owt 21.83 ve © gor * 6 +4.10 +x — 3.
