Chapter 4 Example

Deriving The Equilibrium Constant (K_C) and Equilibrium Conversion(X_e) for a Constant Volume System:

You are given the reversible reaction:

which takes place in a constant volume batch reactor. The equilibrium constant, KC, for this reaction is:

where CAe and CBe are:

Substituting for CAe and CBe gives us:

Substituting known values (CA0 = 0.2 mol/dm3 and KC = 100 dm3/mol):

Solving for the equilibrium conversion, Xe, yields:

Xe = 0.83
