answer !!!
so basically:
To calculate the free energy of a state at 25 degrees Celsius, we can use the formula:
F = E - T*S
Where:
F is the free energy
E is the energy
T is the temperature in Kelvin
S is the entropy
Given:
Energy (E) = 76.5e-21
Degeneracy = 15
Temperature (T) = 25 degrees Celsius
To convert the temperature from Celsius to Kelvin, we add 273.15 to the Celsius temperature:
T = 25 + 273.15 = 298.15 K
To calculate the entropy (S), we can use the formula:
S = k * ln(D)
Where:
S is the entropy
k is Boltzmann's constant (approximately 1.38e-23 J/K)
D is the degeneracy
Substituting the given values into the formula, we have:
S = 1.38e-23 * ln(15)
Calculating the natural logarithm of 15, we find:
S ≈ 1.38e-23 * 2.708
S ≈ 3.729e-23 J/K
Now we can calculate the free energy (F):
F = 76.5e-21 - 298.15 * 3.729e-23
Calculating the product of the temperature and entropy, we find:
F ≈ 76.5e-21 - 1.113e-20
F ≈ -1.035e-20 J
Therefore, the free energy of the state at 25 degrees Celsius is approximately -1.035e-20 Joules.
im not exactly sure if this is right but i hope it at least helps - aydn
