Question

The correct expression for Arrhenius equation showing the effect of temperature on the rate constant is $ (T_2 > T_1) $

• A. $ log_{10}\, \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303\,R} \left[\frac{T_{1}T_{2}}{T_{2}-T_{1}}\right] $
• B. $ log_{10}\, \frac{k_{2}}{k_{1}} = \frac{R}{2.303\,E_{a}} \left[\frac{T_{2}-T_{1}}{T_{1}T_{2}}\right] $
• C. $ log_{10}\, \frac{k_{2}}{k_{1}} = \frac{E_{a}}{R} \left[\frac{T_{2}-T_{1}}{T_{1}T_{2}}\right] $
• D. $ log_{10}\, \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303\,R} \left[\frac{T_{2}-T_{1}}{T_{1}T_{2}}\right] $

Answer 1

Answer: (D)

The effect of temperature on the rate constant was proposed by Arrhenius equation, the correct expression of which is given below:
$log_{10} \frac{k_2}{k_1} = \frac{E_a}{2.303R} (\frac{T_2 -T_1}{T_1T_2})$
