Solution
The value of G (Gibbs free energy) can be calculated using the formula:
G = H - TS
where: H is the enthalpy (-220 kJ/mol), T is the temperature in Kelvin (1000 K), and S is the entropy (-0.05 kJ/(molK)).
Substituting the given values into the formula, we get:
G = -220 kJ/mol - (1000 K * -0.05 kJ/(molK))
G = -220 kJ/mol + 50 kJ/mol
G = -170 kJ/mol
So, the correct answer is B. -170 kJ/mol.
