Answer:
The pressure is
The temperature is
Explanation:
Generally Gibbs free energy is mathematically represented as
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
making P the subject
Now substituting 300 K for T , 2900 J for E ,
for V and
for S
The negative sign signifies the direction of the pressure
Given that
making T the subject
Substituting into the equation
