a
\(\ln \left(\frac{ K _{2}}{ K _{1}}\right)=\frac{ E _{ a }}{ R }\left(\frac{1}{ T _{1}}-\frac{1}{ T _{2}}\right)\)

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

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 \(K=1\)
