$(i)$ ${A_2} \to A + A$ (fast)

$(ii)$ $A + {B_2} \to AB + B$ (slow)

$(iii)$ $A + B \to $ (fast)

$\ln {k_t} = \ln {k_0} + \left( {\frac{{\ln \left( {\frac{5}{2}} \right)}}{{10}}} \right) \times t\left( {t \geqslant 0{}\,^0C} \right)$

$K_0$ =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
