Question

Calculate the ΔG for the following system. Then state if the system is spontaneous or not spontaneous.

Answer 1

+25 kJ; not spontaneous is your answer :) Hope this helps.

Answer 2

Answer:

The correct answer is option B.

Explanation:

Enthalpy of the system = $\Delta H=+25 kJ=25,000 J$

Entropy of the system =$\Delta S=+5.0 J/K$

Temperature of the system =T =23°C = 296 K

The Gibbs's free energy is given by;

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

$\Delta G=25,000 J-296 K\times 5.0 J/K =23,520 J=23.5 kJ$

The value of ΔG is positive which means that system is not spontaneous.

Hence, from the given options the most closest value to our answer is option B.
