For the consecutive reaction `Aoverset(k_1("time"^(-1)))toBoverset(k_2("time"^(-1)))toC` following curves were obtained depending upon the relative values of `k_1 & k_2` .

Now which of the following is the correct match ?

A

Figure 1 `(k_1 lt k_2)`

B

Figure 2 `(k_1 lt k_2)`

C

Figure 2 - `(k_1 gt gt k_2)`

D

Figure 1 - `(k_1 gt gt k_2)`

Text Solution

Verified by Experts

The correct Answer is:
B,D
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`
