Q 1: In order to achieve the same conversion under identical reaction conditions and feed flow rate for a non-autocatalytic reaction of positive order, the volume of an ideal CSTR is
Q 2: The vessel dispersion number for an ideal CSTR is
Q 3: A homogeneous reaction (RβP) occurs in a batch reactor. The conversion of the reactant R is 67 % after 10 minutes and 80 % after 20 minutes. The rate equation for this reaction is
Q 4: A vapor phase catalytic reaction (Q + R β S) follows the Rideal mechanism (R and S are not adsorbed). Initially, the mixture contains only the reactants in an equimolar ratio. The surface reaction step is rate controlling. With constants a and b, the initial rate of reaction (-r0) in terms of total pressure (PT) is given by
