<u>Answer:</u> The heat of hydrogenation of the reaction is coming out to be 234.2 kJ.
<u>Explanation:</u>
Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as
The equation used to calculate enthalpy change is of a reaction is:
For the given chemical reaction:
The equation for the enthalpy change of the above reaction is:
We are given:
Putting values in above equation, we get:
Hence, the heat of hydrogenation of the reaction is coming out to be 234.2 kJ.
Explanation:
The given data is as follows.
Vapour pressure of pure = 33.85 Torr
Temperature = 298 K
Mole fraction of = 122.36 torr
Therefore, calculate the vapor pressure of as follows.
Vapour pressure of = mole fraction of
x K of
= 0.050 x 122.36 Torr
= 6.118 Torr
So, vapor pressure of is 6.118 Torr
.
Now, calculate the vapor pressure of carbon tetrachloride as follows.
Vapour pressure of = mole fraction of
x Pressure of
= (1 - 0.050) × 33.85 Torr
= 32.1575 Torr
So, vapor pressure of is 32.1575 Torr .
Hence, the total pressure will be as follows.
= 6.118 Torr + 32.1575 Torr
= 38.2755 Torr
Therefore, composition of =
= 0.8405
Composition of is 0.8405
.
And, composition of =
= 0.1598
Composition of is 0.1598
.
