For the reaction `A rarr" Product, "-(d[A])/(dt)=k` and at different time interval, [A] values are :

At 20 minute, rate will be :

A

12 mol/min

B

10 mol/min

C

8 mol/min

D

0.4 mol/min

Text Solution

Verified by Experts

The correct Answer is:
D
`A to ` Product
a
`a-x`
Since equal to interval of time equal conc. Decreased then reaction zero order
Rate `= (Delta A)/( Delta t) = (20 -30)/( 20) = (8)/( 20) = 0.4`
