Answer:
1) The correct answer is option b.
2) The correct answer is option a.
Explanation:
1)
At 300 K, the value of the
The and
is related by :
where,
= equilibrium constant at constant pressure
= equilibrium concentration constant
R = gas constant = 0.0821 L⋅atm/(K⋅mol)
T = temperature = 300 K
= change in the number of moles of gas = 1 - 2 = -1
Now put all the given values in the above relation, we get:
The of the reaction = 24.63
Given = [X] = [Y] = [Z] = 1.0 M
Value of reaction quotient = Q
, the equilibrium will move in forward direction that is in the right direction.
2)
At 300 K, the value of the
Given =
Value of reaction quotient in terms of partial pressure =
the equilibrium will move in backword direction that is in the left direction.
Answer: The precipitate formed is
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
