What is the value for G at 500 K if H = 27 kJ/mol and S = 0.09 kJ/(molK)?A.G = 26.9 kJ/molB.G = -18 kJ/molC.G = 0 kJ/molD.G = 72 kJ/molSUBMITarrow_backPREVIOUS
Solution
To find the value of G (Gibbs free energy), we can use the formula:
G = H - TS
where: H = enthalpy = 27 kJ/mol T = temperature = 500 K S = entropy = 0.09 kJ/(molK)
Substituting the given values into the formula, we get:
G = 27 kJ/mol - 500 K * 0.09 kJ/(molK)
G = 27 kJ/mol - 45 kJ/mol
G = -18 kJ/mol
So, the correct answer is B. G = -18 kJ/mol.
