Slope and intercepts of the plots ${\rm{ }}lo{g_{10}}\;K\;{\rm{vs}}\;\frac{1}{T}$ are given respectively by :

$ - \frac{{\Delta {H^ \circ }}}{R},\frac{{\Delta {S^ \circ }}}{R}$

$\frac{{\Delta {H^ \circ }}}{{2.303}},\frac{{ - \Delta {S^ \circ }}}{{2.303\;R}}$

Slope and intercepts of the plots

\mathrm{ }lo{g_{10}}\;K\;\mathrm{vs}\;\frac{1}{T}

are given respectively by :

View answer and explanation

Correct option: C

\frac{{ - \Delta {H^ \circ }}}{{2.303\;R}},\frac{{\Delta {S^ \circ }}}{{2.303\;R}}

Option C is correct because the slope and intercept of the plot log₁₀K vs 1/T are given by -ΔH°/(2.303R) and ΔS°/(2.303R) respectively, according to the van't Hoff equation.
