For the consecutive reaction Aoverset(k_1("time"^(-1)))toBoverset(k_2("time"^(-1)))toCfollowing curves were obtained depending upon the relative values of k_1 & k_2 . Now which of the following is the correct match ?

Answer»

FIGURE 1 `(k_1 lt k_2)`
Figure 2 `(k_1 lt k_2)`
Figure 2 - `(k_1 gt gt k_2)`
Figure 1 - `(k_1 gt gt k_2)`

Solution :For `A OVERSET(k_1)toBoverset(k_2)toC`
In figure 1, [B] increased to a MAXIMUM VALUE during reaction.This is possible when rate of formation of B is more than rate of decay of B in C.
i.e. `k_1 gt gt k_2`
In figure 2, [B] is maintained to a very low value .This means that B is decaying as soon as it is formed.This is possible when `k_2 gt gt k_1`
