<u>Answer:</u> The activation energy of the reaction is 124.6 kJ/mol
<u>Explanation:</u>
To calculate activation energy of the reaction, we use Arrhenius equation, which is:
where,
= equilibrium constant at 79°C =
= equilibrium constant at 26°C =
= Activation energy of the reaction = ?
R = Gas constant = 8.314 J/mol K
= initial temperature =
= final temperature =
Putting values in above equation, we get:
Hence, the activation energy of the reaction is 124.6 kJ/mol
