Thermodynamics · Log k versus 1/t plot

The plot of

\log_{10}K

vs

\dfrac{1}{T}

gives a straight line. The intercept and slope respectively are (where K is equilibrium constant).

(1) $\dfrac{2.303R}{\Delta H^\circ}$ , $\dfrac{2.303R}{\Delta S^\circ}$
(2) $\dfrac{\Delta S^\circ}{2.303R}$ , $-\dfrac{\Delta H^\circ}{2.303R}$
(3) $-\dfrac{\Delta S^\circ R}{2.303}$ , $\dfrac{\Delta H^\circ R}{2.303}$
(4) $-\dfrac{\Delta H^\circ}{2.303R}$ , $\dfrac{\Delta S^\circ}{2.303R}$
