Application of Higher Order Equations

Consider the sequence of reactions following the hrst-order kinetics 

The boundary conditions are derived by eliminating Q from Equation (2.164), 

Equation (2.166), along with the two original and the two new boundary conditions given by Equation (2.167) and Equation (2.168), form a boundary-value problem for Cg. 

Alternatively, substimting the solution of Equation (2.162), which is given by Equation (2.154), into Equation (2.164) gives an equation for Cg that is solved by the method of Green s function
