Tardigrade Admin · Accepted Answer

Activation energy (Ea) can be determined by evaluating rate constants at two different temperatures using the following relation log (k2/k1)=(Ea/2303 R)[(T2-T1/T1 T2)]

Q. The Activation energy of a chemical reaction can be determined by

evaluating rate constant at standard temperature

evaluating velocities of reaction at two different temperatures

evaluating rate constants at two different temperatures

changing concentration of reactants

Activation energy $(E_{a})$ can be determined by evaluating rate constants at two different temperatures using the following relation

$lo g \frac{k _{2}}{k _{1}} = \frac{E _{a}}{2303 R} [\frac{T _{2} - T _{1}}{T _{1} T _{2}}]$
