Answer : The value of equilibrium constant for this reaction at 328.0 K is ![1.70\times 10^{15}](https://tex.z-dn.net/?f=1.70%5Ctimes%2010%5E%7B15%7D)
Explanation :
As we know that,
![\Delta G^o=\Delta H^o-T\Delta S^o](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D%5CDelta%20H%5Eo-T%5CDelta%20S%5Eo)
where,
= standard Gibbs free energy = ?
= standard enthalpy = 151.2 kJ = 151200 J
= standard entropy = 169.4 J/K
T = temperature of reaction = 328.0 K
Now put all the given values in the above formula, we get:
![\Delta G^o=(151200J)-(328.0K\times 169.4J/K)](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D%28151200J%29-%28328.0K%5Ctimes%20169.4J%2FK%29)
![\Delta G^o=95636.8J=95.6kJ](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D95636.8J%3D95.6kJ)
The relation between the equilibrium constant and standard Gibbs free energy is:
![\Delta G^o=-RT\times \ln k](https://tex.z-dn.net/?f=%5CDelta%20G%5Eo%3D-RT%5Ctimes%20%5Cln%20k)
where,
= standard Gibbs free energy = 95636.8 J
R = gas constant = 8.314 J/K.mol
T = temperature = 328.0 K
K = equilibrium constant = ?
Now put all the given values in the above formula, we get:
![95636.8J=-(8.314J/K.mol)\times (328.0K)\times \ln k](https://tex.z-dn.net/?f=95636.8J%3D-%288.314J%2FK.mol%29%5Ctimes%20%28328.0K%29%5Ctimes%20%5Cln%20k)
![k=1.70\times 10^{15}](https://tex.z-dn.net/?f=k%3D1.70%5Ctimes%2010%5E%7B15%7D)
Therefore, the value of equilibrium constant for this reaction at 328.0 K is ![1.70\times 10^{15}](https://tex.z-dn.net/?f=1.70%5Ctimes%2010%5E%7B15%7D)

Answer:
Far right
Explanation:
The qualities indicated here are of the element Sulphur (S) and any element of same qualities i.e color pale yellow, nature solid, electrical conductivity none, should be placed at far right corner of the periodic table or position 3 mentioned in the attached picture.
Hope it help!
Explanation:
Derived quantities are quantities that are calculated from two or more measurements. They include area, volume, and density. The area of a rectangular surface is calculated as its length multiplied by its width. The volume of a rectangular solid is calculated as the product of its length, width, and height.
