Answer:
The pressure is ![P= - 6.39*10^8Pa](https://tex.z-dn.net/?f=P%3D%20-%20%206.39%2A10%5E8Pa)
The temperature is ![T =1218.63 K](https://tex.z-dn.net/?f=T%20%3D1218.63%20K)
Explanation:
Generally Gibbs free energy is mathematically represented as
![G = E + PV -TS](https://tex.z-dn.net/?f=G%20%3D%20E%20%2B%20PV%20-TS)
Where E is the enthalpy
PV is the pressure volume energy (i.e PV energy)
S is the entropy
T is the temperature
For stability to occur the Gibbs free energy must be equal to zero
Considering Diamond
So at temperature of T = 300 K
![E + PV - TS = 0](https://tex.z-dn.net/?f=E%20%2B%20PV%20-%20TS%20%3D%200)
making P the subject
![P = \frac{TS-E}{V}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7BTS-E%7D%7BV%7D)
Now substituting 300 K for T , 2900 J for E ,
for V and
for S
![P = \frac{(300 * 2.38)- 2900}{3.42*10^{-6}}](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B%28300%20%2A%202.38%29-%202900%7D%7B3.42%2A10%5E%7B-6%7D%7D)
![P= - 6.39*10^8Pa](https://tex.z-dn.net/?f=P%3D%20-%20%206.39%2A10%5E8Pa)
The negative sign signifies the direction of the pressure
Given that ![P = 1*0^5Pa](https://tex.z-dn.net/?f=P%20%3D%201%2A0%5E5Pa)
making T the subject
![T = \frac{PV+E}{S}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7BPV%2BE%7D%7BS%7D)
Substituting into the equation
![T = \frac{1*10^5 * 3.42 *10^{-6}+2900}{2.38}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B1%2A10%5E5%20%2A%203.42%20%2A10%5E%7B-6%7D%2B2900%7D%7B2.38%7D)
![T =1218.63 K](https://tex.z-dn.net/?f=T%20%3D1218.63%20K)
