Chemical Reaction Engineering Pick out the wrong statement pertaining to space velocity of flow reactors. None of these The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor None of these The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour The unit of space velocity is (time)⁻¹ The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by keff = (k+ kg)/2 1/keff = 1/k + 1/kg keff = k + kg keff = (kkg)1/2 keff = (k+ kg)/2 1/keff = 1/k + 1/kg keff = k + kg keff = (kkg)1/2 ANSWER DOWNLOAD EXAMIANS APP
