Construct a ConversionTemperature Diagram for a Reversible Adiabatic Reaction
A reversible reaction, A ↔ B, takes place in an adiabatic plugflow reactor (PFR). Construct a conversionversustemperature 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.

For the reversible reaction A ↔ B with both reactant A and inert component I in the adiabatic PFR feed, the equilibrium constant is:
where K_{m} is the equilibrium constant at temperature T_{m} (K), Δ His the heat of reaction (J/mol), R is the ideal gas constant (J/mol K), and T is the temperature of the reaction (K).
The equilibrium conversion is obtained from the equilibrium constant, assuming ideal gases:
where X_{e} is the equilibrium conversion, X_{EB} is the conversion calculated from the energy balance, α is the ratio in the molar flow rate of inert to reactant, C_{P} is the heat capacity (J/mol K), and T_{f} is the feed temperature (K).
