The first order series reaction 
is conducted in a batch reactor. The initial concentrations of A, B and C (CA0, CB0, CC0 respectively) are all non-zero. The variation of CB with reaction time will not show a maximum, if
is conducted in a batch reactor. The initial concentrations of A, B and C (CA0, CB0, CC0 respectively) are all non-zero. The variation of CB with reaction time will not show a maximum, if22.
A second order reaction of the form A + B 
C is called a pseudo-first order reaction, when
C is called a pseudo-first order reaction, when23.
Pick out the wrong statement.
In a first order reaction, A products; the reaction becomes slower as it proceeds, because the concentration of A decreases and the rate is proportional to the concentration of A.
products; the reaction becomes slower as it proceeds, because the concentration of A decreases and the rate is proportional to the concentration of A.Transition state theory approaches the problem of calculating reaction rates by concentrating on the idea of activated complexes.
According to the penetration theory, the mass transfer co-efficient decreases, if the exposure time of an eddy to the solute decreases.
If the rate of an irreversible reaction, A + B 2C is k.CA.CB, then the reaction is always elementary.
2C is k.CA.CB, then the reaction is always elementary.24.
Effectiveness factor (E) of a catalyst pellet is defined as, 
Effectiveness factor for a first order reaction is given by (where, T = Thiele modulus)
Effectiveness factor for a first order reaction is given by (where, T = Thiele modulus)25.
