Answer:

When talking about the available energy within the cells, we're talking about <em>"Free Energy"</em>, which is the kind of energy available to do work; and if we express that concempt into a thermal environment, that kind of energy is also known as potential energy; that energy in the cells is stored by ATP molecules and later on moved from one part of the cell to another, where it can be used for other biochemical purposes. Thereby (C.)

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 .

Best regards!
