Answer : The equilibrium pressure is,
Explanation :
The given balanced chemical reaction is,
First we have to calculate the standard free energy of reaction .
where,
= standard free energy of reaction = ?
n = number of moles
Now put all the given values in this expression, we get:
Now we have to calculate the value of
where,
= standard Gibbs free energy = -90.72 kJ/mol
R = gas constant = 8.314 J/mole.K
T = temperature = 298 K
= equilibrium constant = ?
Now put all the given values in this expression, we get:
Now we have to calculate the value of .
The given balanced chemical reaction is,
The expression for equilibrium constant will be :
In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Let the equilibrium pressure be, x
Pressure of = Pressure of
= x
Now put all the given values in this expression, we get
Thus, the equilibrium pressure is,

To solve this question, we need to use the Avogadro's Number, which is a constant first discovered by Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are 6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:
So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent 14,12 moles of Na₂SO₃
Have a nice day!
