An elementary irreversible liquid-phase reaction, 2P ⟶ Q, where the rate constant k = 2 L mol⁻¹ min⁻¹, takes place in an isothermal non-ideal reactor. The E-curve in a tracer experiment is shown in the figure. Pure P (2 mol L⁻¹) is fed to the reactor. Using the segregated model, the percentage conversion of P at the exit of the reactor is __________% (rounded off to the nearest integer).
