Answer: 5.85kJ/Kmol.
Explanation:
The balanced equilibrium reaction is

The expression for equilibrium reaction will be,
![K_p=\frac{[p_{D}]\times [p_{C}]}^4{[p_{B}]^2\times [p_{A}]}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%5Bp_%7BD%7D%5D%5Ctimes%20%5Bp_%7BC%7D%5D%7D%5E4%7B%5Bp_%7BB%7D%5D%5E2%5Ctimes%20%5Bp_%7BA%7D%5D%7D)
Now put all the given values in this expression, we get the concentration of methane.


Relation of standard change in Gibbs free energy and equilibrium constant is given by:

where,
R = universal gas constant = 8.314 J/K/mole
T = temperature = 
= equilibrium constant = 10.6



Thus standard change in Gibbs free energy of this reaction is 5.85kJ/Kmol.
Answer:
Cause/ effect relationship.
Explanation:
because the force is the cause of energy that is present and velocity is the effect (speed) that is present.
Your answer would be 0.024951344877489 but rounding it would be 0.025 moles
It's a mixture of H2O + a soluble substance like, salt.
