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)`

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 of reaction at 40th sec. will be change in a volume during a small interval of time close to 40 sec. viz. 40-30,50-40, 50-30 or 40-20 sec. Thus `(V_4 -V_2)/(50-30 )`is not the correct option because volume change during the interval 50-30 sec. `= V_5-V_2` and not `V_4 -V_2`.
