At a certain temperature, the value of the slope of the plot of osmotic pressure `(pi)` against concentration (`"C in mol L"^(-1)`) of a certain polymer solution is 291R. The temperature at which osmotic pressure is measured is (R is gas constant)

A

`271^(@)C`

B

`18^(@)C`

C

564 K

D

18 K

Text Solution

Verified by Experts

The correct Answer is:
B
`pi=CRT`
Slope of graph = `(pi)/(C)=RT`
RT = 291 R
T = 291 K
`T=(291-273)^(@)C=18^(@)C`.
