Answer The value of 
and 
is, 40.79 kJ and 37.7 kJ respectively.
Explanation :
Heat released at constant pressure is known as enthalpy.
The formula used for change in enthalpy of the gas is:
Now we have to calculate the work done.
Formula used :
where,
w = work done = ?
P = external pressure of the gas = 1 atm
= initial volume = 
= final volume = 
Now put all the given values in the above formula, we get:
Now we have to calculate the change in internal energy.
Thus, the value of and is, 40.79 kJ and 37.7 kJ respectively.
The solution would be like
this for this specific problem:
<span>(78.6 kJ) / (92.0 g /
(46.0684 g C2H5OH/mol)) = 39.4 kJ/mol </span>
<span>39.3 </span>
So the approximate molar
heat of vaporization of ethanol in kJ/mol is 39.3.
I hope this answers your question.
A catalyst is a substance added to the reaction that lowers the activation energy by providing an alternate pathway for the reactions to go to completion.
A catalyst is a substance that accelerates a chemical response, or lowers the temperature or strain needed to begin one, with out itself being ate up at some stage in the response. Catalysis is the procedure of adding a catalyst to facilitate a response.
Catalysts may be categorized as homogeneous, heterogeneous, or enzymatic. Homogeneous catalysts exist inside the identical phase as the reactants, whereas heterogeneous catalysts exist in a exclusive section than the reactants.
Catalysts are basically categorised into 4 kinds.Homogeneous, Heterogeneous, Heterogenized homogeneous catalyst and Biocatalysts. Homogeneous catalyst: In homogeneous catalysis, reaction mixture and catalyst both are gift inside the equal segment.
