The correct value of the gas constant 'R...

The correct value of the gas constant 'R' is close to

A

`0.082 " L atm K"`

B

`0.082" L atm K"^(-1)"mol"^(-1)`

C

`0.082" L atm"^(-1) "K mol"^(-1)`

D

`0.082L^(-1)"atm"^(-1)"K mol"`

Text Solution

Verified by Experts

The correct Answer is:
B
The numerical value of R depends upon the units in which pressure and volume are expressed. When pressure is expressed in atmosphere and volume in litres, then the value of R at STP for 1 mole of gas is
`R=("1 atm"xx22.414L)/("1 mole"xx273.15K)`
`=0.082" L atm K"^(-1)"mol"^(-1)`
