the rate constant of the reaction A to...

the rate constant of the reaction `A to B` is `0.6xx10^(-3)` mole per second . If the concentration of A is 5M then concentration of B After 20 min is

A

0.36 M

B

0.72 M

C

1.08 M

D

3.60 M

Text Solution

Verified by Experts

The correct Answer is:
B
Zero order reaction
x=kt
`x=0.6xx10^(-3)xx20xx60`
`=72xx10^(-2)`
x=0.72M
`{:(,Ato,B),("Initial case",5,0),("After 20 min.",5-x,x):}`
So, [B]=x=0.72M
