Answer:
The value of activation barrier for the reaction is, 43.374 kJ/mol.
Explanation:
According to the Arrhenius equation,
or,
where,
= rate constant at = k
= rate constant at = 3k
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mol.K
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get
Therefore, the activation energy for the reaction is, 43.374 kJ/mol.

</span>P (power of laser) = 3,2 mW = 0,0032 W.
λ (wavelength) = 633 nm = 633 · 10⁻⁹m = 6,33·10⁻⁷m.
