Chemical Engineering > GATE 2010 > Non-Ideal Reactors
Two reactors (reactor 1 and reactor 2) with average residence times, τ1 and τ2 respectively. are placed in series. Reactor 1 has zero dispersion and reactor 2 has infinite dispersion. The residence-time distribution. E(t) of this system. is given by
A
{0, t≤τ1; (1/τ2)exp(-(t-τ1)/τ2), t>τ1}
B
{0, t≤τ2; (1/τ1)exp(-(t-τ2)/τ1), t>τ2}
C
{0, t≤τ1; (1/τ1)exp(-(t-τ1)/τ2), t>τ1}
D
{0, t≤τ2; (1/τ2)exp(-t/τ1), t>τ2}

Correct : a
