For the following three reactions I, II and III, equilibrium constants are given:
(I) 
(II) 
(III) 
Which of the following relations is correct?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Write down the given reactions with their equilibrium constants:
Reaction (II): 
Reaction (I): 
Adding these two reactions term by term gives:
(which is reaction (III))
When two equilibria are added, their constants multiply.
Hence:
