Answer:
Explanation:
Given that:
Pressure P = 10 atm
number of moles of N
= 1 mole
correction for the attractive force between molecule a = 1.352
correction for the volume of molecules b = 0.0387 L mol-1
Rate = 8.314
critical Temperature Tc= 126.3 K
Using van deer Waal equation:
So for 1 mole of N gas; we have
Recall that: Tc = 
and
Vc = 3b
Thus;
Vc= 3×(0.0387)
Vc = 0.1161m³
using the above Van der Waal equation, the value of V can also be determined, but in several situations, we abandon the term of (V - nb) and sometimes abandon 
depending on the circumstances.
Hydrophobic in simple terms is the "fear" of water.
In chemistry, Ionic salts are technically hydrophilic as they will dissolve in water.
most fats and oils or triesters won't why?
salts are made from ions and their structure contain polar bonds Na+ and Cl-
Fats and oils tend to not have these.
Fats and oils contain many carbon covalent bonds which are non-polar which tend to make the molecule non-polar as a whole, therefore, it can't dissolve in water and is said to be hydrophobic.
Hope that heps :)
NB included a diagram to help.
We have the value of
Total energy produced in the chemical reaction=653 550 KJ
Time needed=142.3min
To calculate the rate of energy transfer, that is the amount of energy produced per minute.
Rate of energy transfer=
=
=4592.76 KJ min⁻¹
So, the rate of energy transfer is 4592.76 KJ min⁻¹.
