List I and List II contains four entries each. Entries of List I are to be matched some entries of List II. One or more than one entries of List I may have the match with the same entry of List II.

Answer 1

$\frac{K_{10+T^{o}C}}{K_{T^{o}C}}=2$ means as we increase temp. value of K increases so reaction goes forward means a endothermic reaction.
$\frac{K_{10+T^{o}C}}{K_{T^{o}C}}=1/2$ means as we increase temp. value of K decreases so reaction goes backward means a exothermic reaction.
