Activation energy of any chemical reaction can be calculated if one knows the value of
A
orientation of reactant molecules during collision.
B
rate constant at two different temperatures.
C
rate constant at standard temperature.
D
probability of collision.
Detailed Solution
The activation energy of a reaction can be determined by evaluating the rate constants at two different temperatures, using the Arrhenius equation:
$\log\frac{k_2}{k_1} = \frac{E_a}{2.303R}\left(\frac{T_2 - T_1}{T_1T_2}\right)$
