The normal boiling point of a liquid `X` is 400 K. Which of the following statement is true about the process X (l) 
X(g)?
A
At 400 K and 1 atm pressure 
G = 0
G = 0
B
At 400 K and 2 atm pressure 
G = + ve
G = + ve
C
At 400 K and 0.1 atmpresure 
G = – ve
G = – ve
D
At 410 K and 1 atm pressure 
G = + ve
G = + ve
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
Boiling of a liquid at normal boiling point is a equilibrium process and on decreasing the pressure equilibrium will go forward and 
G will be negative and vice versa.
