What is the value for AG at 5000 K if AH = -220 kJ/mol and S= -0.05 kJ/(mol-K)?

Serhud [2]

Answer:

C. 30 kJ

Explanation:

Hello there!

In this case, in agreement to the thermodynamic definition of the Gibbs free energy, in terms of enthalpy of entropy:

$\Delta G= \Delta H-T\Delta S$

It is possible to calculate the required G by plugging in the given entropy and enthalpy as shown below:

$\Delta G=-220kJ/mol-5000K*-0.05kJ/mol*K\\\\\Delta G=30kJ/mol$

Therefore, the answer is C. 30 kJ .
