Choose an option
Show full solutionCorrect option: D
Correct answer
D
Step-by-step explanation
The relationship between and is given by , where .
Given K and L atm K mol.
The value of .
For case (i): and .
.
Since , we have .
Checking options for (i):
(1)
(2)
(3)
(4) . This matches.
For case (ii): and .
.
Since , we have .
Checking option (4) for (ii): . This also matches.
Thus, for (i) and for (ii) .
Given K and L atm K mol.
The value of .
For case (i): and .
.
Since , we have .
Checking options for (i):
(1)
(2)
(3)
(4) . This matches.
For case (ii): and .
.
Since , we have .
Checking option (4) for (ii): . This also matches.
Thus, for (i) and for (ii) .
