For the reaction A(g)+B(g)C(g)+D(g) the equilibrium constant K is defined as K=yAyByCyD where y is the molar fraction of the gas phase of a species. At 620.00K, the equilibrium constant is 2.000 . Suppose the feed to a reactor contains 3.200molA and 2.500 mol B, contains no C or D, and reaches equilibrium at 620.00K. What is the extent of reaction, e, at equilibrium? e= What is the equilibrium mole fraction of each gas? yA= yB= yC= yD=
