For a tubular reactor with space time \'τ\' and residence time \'θ\', the following statement holds good.
The first order series reaction is conducted in a batch reactor. The initial concentrations of A, B and C ( C A 0 , C B 0 , C C 0 respectively) are all non-zero. The variation of C B with reaction time will not show a maximum, if
A first order reaction A B occurs in an isothermal porous catalyst pellet of spherical shape. If the concentration of A at the centre of the pellet is much less than at the external surface, the process is limited by
The effectiveness factor for large value of Thiele modulus ( L K / D 1 ) of a solid catalysed first order reaction is equal to (where, L = length of the reactor, cm, D 1 = diffusion co-efficient, cm 2 /second)
In a chemical reaction, repesented by, , it is observed that the (i) rate of reaction increases by a factor of 4 on doubling the concentration of the reactant. (ii) rate of reaction increases by a factor of 9 on trebling the concentration of the reactant. Then the rate of the reaction is proportional to(where, C A = contentration of the reactant)
The rate of a gas phase reaction is given by K . C A . C B . If the volume of the reaction vessel is reduced to l/4th of its initial volume, then the reaction rate compared to the original rate will be __________ times.
Effectiveness factor ( E ) of a catalyst pellet is defined as, Effectiveness factor for a first order reaction is given by (where, T = Thiele modulus)
A second order reaction of the form A + B C is called a pseudo-first order reaction, when
What is the value of ' n ' if the reaction rate of the chemical reaction A B , is proportional to C A n and it is found that the reaction rate triples, when the concentration of ' A ' is increased 9 times ?
