$\ln {k_t} = \ln {k_0} + \left( {\frac{{\ln \left( {\frac{5}{2}} \right)}}{{10}}} \right) \times t\left( {t \geqslant 0{}\,^0C} \right)$
$K_0$ =rate constant at $0\,^o C$ ; $k_t$ = rate constant at $t\,^o C$
Temperature coefficient of reaction, assuming that the rate constant increases same number of times on each $10\,^oC$ rise in temperature, is
| List $-I$ | List $-II$ |
| $(A)$ Benzaldehyde | $(i)$ Phenolphthalein |
| $(B)$ Phthalic anhydride | $(ii)$ Benzoincondensation |
| $(C)$ Phenyl benzoate | $(iii)$ Oil of wintergreen |
| $(D)$ Methyl salicylate | $(iv)$ Friesre arrangement |
When $P$ is going to form $PF_5$, then these radial distances are going to become arbitrarily ____,____and ____ respectively
$0.48 + \log \left\{ { - \frac{{d[A]}}{{dt}}} \right\} = \log \left\{ { + \frac{{d[B]}}{{dt}}} \right\} + 0.7$
Then, $x : y$ is
