Answers
Answer -
Explanation -
Given:-
- Initial pressure of = 100 mm
- Mole fraction of
Find:-
Value of
Solution:-
and
It is given that, initially is 100 mm.
At Initial) 100mm............... 0 . .............. 0
At Equilibrium) (100 - C).... C ................ C
When non-volatile solute is added to a solvent, then vapour pressure of solvent decreases because some of the space is occupied by solute particles which create hindrance to the formation of particles.
Vapour pressure of solution is equal to the partial pressure of solvent.
So,
Here -
- is mole fraction
- is partial pressure
- is total pressure
...(1)
Similarly,
...(2)
Add equation (1) & (2)
Now,
Answer:
Explanation:
Given,
A chemical Equation,
Initial Pressure of = 100 mm
At equlibrium,
Mole fraction of CO =
Since,
Both CO and have equal moles.
Therefore,
Mole fraction of =
Now,
Let the amount of dissociated in terms of partial pressure is ‘c’ mm.
Therefore,
We have the following conditions.
Refer to the attachment for Equation.
Now,
We have,
Partial Pressure of,
Let the Total Pressure =
We know that,
Therefore,
We have,
Also,
Adding the Equation (1) and (2),
We get,
Therefore,
We have,
Now,
We know that,
Therefore,
Putting the values,
We get,
