The half-life period of a first-order reaction is 15 minutes. The amount of substance left after one hour will be:

A

`A_0/4`

B

`A_0/8`

C

`A_0/16`

D

`A_0/32`

Text Solution

Verified by Experts

The correct Answer is:
2

`Z=(PV_(m))/(RT)gt1`
`(PM_(m))/(RT)=(1xx22.4)/(RxxT)`
At same pressure `=1atm`
`(1xxV_(m))/(RT)gt(1xx22.4)/(RxxT)rArrV_(m)gt22.4L` at STP for real gas.
