Chemical Reaction Engineering Pick out the wrong statement pertaining to space velocity of flow reactors. The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor 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 None of these 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 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 None of these The unit of space velocity is (time)⁻¹ ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If the pore diffusion controls in a catalytic reaction, the apparent activation energy Ea is equal to (E + ED)/2 ED/2 (E + ED) where ED is activation due to diffusion The intrinsic activation energy E (E + ED)/2 ED/2 (E + ED) where ED is activation due to diffusion The intrinsic activation energy E ANSWER DOWNLOAD EXAMIANS APP
