For the reaction

A \rightleftharpoons B

at a single constant temperature, two sets of equilibrium measurements were recorded: • When

K = 12

\Delta G^\circ = -3.1\,\text{kJ/mol}

. • When

K = 1.3 \times 10^{-1}

\Delta G^\circ = +1.3\,\text{kJ/mol}

. Using only these data, calculate the temperature of the system in kelvins.
