A straight line obtained from plotting

\Delta G^{\circ}

(in kJ mol⁻¹) versus

\ln K

for several reactions has a slope of –7.43 kJ mol⁻¹ per unit of

\ln K

. Using

R = 8.314\,\text{J mol}^{-1}\,\text{K}^{-1}

, what is the temperature represented by the data? (a)

388\;\text{K}

(b)

2.06\times10^{3}\;\text{K}

(c)

900\;\text{K}

(d)

600\;\text{K}
