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

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 -

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 first 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))] When k_(1)=1s^(-1) and k_(2)=500s^(-1) , select most appropriate graph a) b) c) d)

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 ?
