A reaction has AH° = 300 kJ/mol and
AS° = 50 J/mol·K.
a. Determine AG°rxn at 125°C.
b. Is the reaction spontaneous at the
temperature in Part A? If not, under
what temperature conditions
will it become spontaneous? Hint: Look
at the signs of AH° and AS°, now what
kind of temperature
condition was mentioned in the notes
that would make the reaction
spontaneous.

Step 1

$\begin{array}{rcl} G i v e n d a t a, \\ ∆ H & = & 300 k J / m o l \\ ∆ S & = & 50 J / m o l . K \\ = & 0.050 k J / m o l . K \\ T e m p e r a t u r e & = & 125^{o} C \\ = & 125 + 273 \\ = & 398 K \end{array}$
