The elementary liquid-phase irreversible reactions
k1 = 0.4 min-1 A → B
k2 = 0.1 min-1 → C
take place in an isothermal ideal CSTR (Continuous-Stirred Tank Reactor). Pure A is fed to the reactor at a concentration of 2 mol/Liter. For the residence time that maximizes the exit concentration of B, the percentage yield of B, defined as (net formation rate of B / consumption rate of A) × 100, is ______ (rounded off to the nearest integer).
