Consider the graph given in figure . ...

Consider the graph given in figure . Which of the following options does not show instantaneous rate of reaction at 40 ?

A

`(V_(5)-V_(2))/(50-30)`

B

`(V_(4)-V_(2))/(50-30)`

C

`(V_(3)-V_(2))/(40-30)`

D

`(V_(3)-V_(1))/(40-20)`

Text Solution

Verified by Experts

The correct Answer is:
B
Instantaneous rate at 40th sec. will be change in volume during small interval of time close to 40 sec. viz. `40-30,50-40,50-30" or "40-20` sec. Volume change during `50-30` sec. interval `=V_(5)-V_(2)` and not `V_(4)-V_(2)`. Hence, (b) is not correct.
