Question

What is the triangle G at 294K for the following process at 1.0 atm?

Answer 1

The ΔG is 3.66 kJ.

To calculate the ΔG of a chemical reaction, it is necessary to use the ΔG formula and replace the values. Remember to convert the J into kJ before the calculation:

$\begin{gathered} \Delta G=\Delta H-T\cdot\Delta S \\ \Delta G=31.0\frac{kJ}{mol}-294K\cdot0.093\frac{kJ}{\text{mol}\cdot K} \\ \Delta G=3.66\frac{kJ}{mol} \end{gathered}$

So, the ΔG of the reaction is 3.66 kJ.
