$\operatorname{\ell n}\left(\frac{ K _{2}}{ K _{1}}\right)=\frac{532611}{8.3}\times\left(\frac{10}{310 \times 300}\right)$

where $K _{2}$ is at $310 \,K$ and $K _{1}$ is at $300 \,K$ $\ln \left(\frac{ K _{2}}{ K _{1}}\right)=6.9$

$=3 \times \ell n 10$

$\ell n \frac{ K _{2}}{ K _{1}}=\ell n 10^{3}$

$K _{2}= K _{1} \times 10^{3}$

$K _{1}= K _{2} \times 10^{3}$

So $K=1$
