For the consecutive unimolecular-type first-order reaction `A overset(k_(1))rarr R overset(k_(2))rarr S`, the concentration of component R, `C_( R)` at any time `t` is given by -
`C_(R ) = C_(OA)K_(1)[e^(-k_(1)t)/((k_(2)-k_(1))) +e^(-k_(2)t)/((k_(1)-k_(2)))]`
if `C_(A) = C_(AO), C_(R ) = C_(RO) = 0` at `t = 0`
The time at which the maximum concentration of `R` occurs is -

For the consecutive unimolecular first order reaction A overset(k_(1))rarr R overset(k_(2))rarr S , the concentration of component A , C_(A) at any time t is given by

A consecutive reaction, A overset(K_(1))(rarr)B overset(K_(2))(rarr)C is characterised by:

For the two step reaction in which both the steps are first order R overset(k_(1))rarr I I overset(k_(2))rarr P the rate of change of concentration of I is given by the plot

Mechanism of the reaction is: A overset(k_(1))rarrB, 2Aoverset(k_(2))rarr C + D What is (-d[A])/(dt) ?

Mechanism of the reaction is: A overset(k_(1))rarrB, 2Aoverset(k_(2))rarr C + D What is (-d[A])/(dt) ?

Two consecutive irreversible fierst order reactions can be represented by Aoverset(k_(1))(rarr)Boverset(k_(2))(rarr)C The rate equation for A is readily interated to obtain [A]_(t)=[A]_(0).e^(-k_(1^(t))) , and [B]_(t)=(k_(1)[A]_(0))/(k_(2)-k_(1))[e^(-k_(1)^(t))-e^(-k_(2)^(t))] At what time will B be present in maximum concentration ?

In the sequence of reaction A overset(k_1) rarr B overset(k_2)rarr C overset(k_3) rarr D K_3>K_2>K_1 , then the rate determining step of the reaction is

Two consecutive irreversible fierst order reactions can be represented by Aoverset(k_(1))(rarr)Boverset(k_(2))(rarr)C The rate equation for A is readily interated to obtain [A]_(t)=[A]_(0).e^(-k_(1^(t))) , and [B]_(t)=(k_(1)[A]_(0))/(k_(2)-k_(1))[e^(-k_(1)(t))-e^(-k_(2)(t))] At what time will B be present in maximum concentration ? a) (K_(1))/(K_(2)-K_(1)) b) (1)/(k_(1)-k_(2) In (k_(1))/(k_(2)) c) (1)/(k_(2)-k_(1)) In (k_(1))/(k_(2)) d) none of these
