Reverse reaction will go to completion.
only and (E) only
only and (E) only
D
When 1 mole of 
changes into equilibrium mixture, value of 
(E) When 2 mole of
changes into equilibrium mixture, 
for equilibrium mixture is 
.
Choose the correct answer from the options given below:
and (E) only only
changes into equilibrium mixture, value of (E) When 2 mole of
changes into equilibrium mixture, for equilibrium mixture is . Choose the correct answer from the options given below: and (E) only only
Text Solution
Verified by ExpertsThe correct answer is:
A
From the graph of G vs fraction of 
dissociated:
At 
(pure 
): 
At equilibrium 
: 
(minimum)
At 
(complete dissociation): 
Statement 
(positive), not 
. False.
Statement Even with positive 
, equilibrium is established with partial dissociation. False.
Statement Reverse reaction reaches equilibrium, not completion. False.
Statement 
. True.
Statement (E) 
. True.
