Question:
For the equilibrium , is equal to four times the total pressure. The number of moles of 'A' formed is
Answer:
option (4) 2/√5
Explanation:
Let the total equilibrium pressure be P atm
is four times the total pressure.
Let the degree of dissociation be α
1 0 0 ( initially)
1 - α α α (at equilibrium)
Total number of moles at equilibrium = 1 - α + α + α
= 1 + α
Now, let's find the partial pressures of AB, A and B
Partial pressure of AB :
Partial pressure of A :
Partial pressure of B :
The expression of for the given equation is
Substitute,
The number of moles of 'A' formed is 2/√5
