Answer:
Vapor pressure of pure water: 3.1690 kPa
Explanation:
Vapor pressure is P=0.955(3.1690)=3.0263 kPa
Change in vapor pressure : 3.169-3.0263=0.142 kPa
Answer with Explanation:
Ionic bond:It is that type of bond which formed between negative and positive ions.
Hydrogen bonding:Hydrogen bonding formed between hydrogen and high electronegative elements.
Dispersion force:It is weakest intermolecular force.It is temporary attractive force.When electrons of two adjacent atoms occupy positions that make the atoms temporary dipoles.
NaCl: In which Na is positive ion and Cl is negative ion.
Therefore, NaCl is ionic.
HF:F is highest electronegativ elements.
HF:Hydrogen bonding
HCl: Hydrogen bonding
:Dispersion
Answer:

Explanation:
Hello,
In this case, for the given reaction, the equilibrium constant turns out:
![Keq=\frac{[B]}{[A]}=\frac{0.5M}{1.5M} =1/3](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D%3D%5Cfrac%7B0.5M%7D%7B1.5M%7D%20%3D1%2F3)
Nonetheless, we are asked for the reverse equilibrium constant that is:

Which is greater than one.
In such a way, the Gibbs free energy turns out:

Now, since the reverse equilibrium constant is greater than zero its natural logarithm is positive, therefore with the initial minus, the Gibbs free energy is less than zero, that is, negative.
