A reversible reaction, A ↔ B, takes place in an adiabatic plug-flow reactor (PFR). Construct a conversion-versus-temperature diagram by plotting the energy balance and equilibrium lines. The energy balance line is plotted first for a feed that contains only reactant A, and then it is plotted for a feed that also contains an inert component. Click the “new problem” button for a new set of conditions. Before moving on to the next step, check “solution” to see the answer. Once you check “solution”, you cannot change your answer.
