The following elementary liquid-phase equilibrium reaction takes place in a batch reactor system: A R. The initial concentrations of A and R are 0.5 and 0.0molL1, respectively. At t=8 minutes, the conversion of A is 0.33 . At equilibrium the conversion of A is 0.667 . The rate of destruction of A may be expressed as: rA=k1CAk2CR What is the value of k2, expressed in the mol, L, minute system of units, to three decimal places. Note that this problem does not require plotting. Remember the definition of equilibrium conversion
