Chemical kinetics

  1. Oct 28, 2008 #1
    1. The problem statement, all variables and given/known data
    Write down the material balance for the components A, B, C, D id this reaction takes place in a batch reactor:

    A+B[tex]\Updownarrow[/tex]C and C+B[tex]\Updownarrow[/tex]D

    The difunctional starting material (A) combines with the primary reactant (B) to form a monofunctional intermediate (C), which subsequently combines with B to produce the final desired product (D).

    2. Relevant equations
    (dC_j/dt)=R_j

    r_1=k_1*C_A*C_B-k_-1*C_C
    r_2=k_2*C_B*C_C-k_-2*C_D


    3. The attempt at a solution

    Okay i know that (dC_A/dt)=-r_1, (dC_B/dt)=-r_1-r_2, (dC_C/dt)=r_1-r_2, and (dC_D/dt)=r_2
    I've also assumed that C_A(0)=C_A0, C_B(0)=C_B0, C_C(0)=0 and C_D(0)=0
    I don't know how to go about solving the rest. please help.
