    Some please help me with an ODE problem!!

    ptc-3984262 Copper

      So for my Kinetics class I'm trying to derive a function in Mathcad to get the result I need to answer a question in the book.  First I need to verify that Mathcad can do this.  Can someone please tell me how to do this?  Thanks!

       

      Irreversible 1st order reaction in PFTR (Parallel Reaction)

       

      A→B   r1=k1*Ca

       

      A→C  r2=k2*Ca

       

       

      dCa/dt=-k1*Ca-k2*Ca

       

      dCb/dt=k1*Ca

       

      dCc/dt=k2*Ca

       

      Boundary Condition:  Ca=Ca0

       

      Ca(t)=Ca0*exp(-(k1+k2)*t)
