The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically writ

Alex17521 [72]

Answer:

T = 42.08 °C

Explanation:

Using the expression,

$\ln \dfrac{k_{1}}{k_{2}} =-\dfrac{E_{a}}{R} \left (\dfrac{1}{T_1}-\dfrac{1}{T_2} \right )$

Wherem

$k_1\ is\ the\ rate\ constant\ at\ T_1$

$k_2\ is\ the\ rate\ constant\ at\ T_2$

$E_a$ is the activation energy

R is Gas constant having value = 8.314 J / K mol

Thus, given that, $E_a$ = 45.6 kJ/mol = 45600 J/mol (As 1 kJ = 1000 J)

$k_2=2\times k_1$

$k_1=0.0160s^{-1}$

$T_1=30\ ^0C$

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T = (30 + 273.15) K = 303.15 K

$T_1=303.15\ K$

So,

$\ln \dfrac{k_{1}}{2\times k_{1}} =-\dfrac{45600}{8.314} \left (\dfrac{1}{303.15}-\dfrac{1}{T_2} \right )$

$\ln \dfrac{1}{2} =-\dfrac{45600}{8.314} \left (\dfrac{1}{303.15}-\dfrac{1}{T_2} \right )$

$8.314\ln \left(2\right)=-45600\left(\frac{1}{303.15}-\frac{1}{T_2}\right)$

$8.314\ln \left(2\right)=-150.42058+\frac{45600}{T_2}$

$144.65775 =\frac{45600}{T_2}$

$T_2=\frac{45600}{144.65775}$

$T_2=315.23\ K$

Conversion to °C as:

T(K) = T( °C) + 273.15

So,

315.23 = T( °C) + 273.15
