Autoionization Reactions are those reactions in which ions or molecules ionizes spontaneously without adding any external reagent.
For Example,
Autoionization of water.
H₂O + H₂O ⇆ H₃O⁺ + OH⁻
Autoionization reaction of Methanol is shown below,
For Example,
Autoionization of water.

Answer : The activation energy of the reaction is,
Solution :
The relation between the rate constant the activation energy is,
where,
= initial rate constant =
= final rate constant =
= initial temperature =
= final temperature =
R = gas constant = 8.314 kJ/moleK
Ea = activation energy
Now put all the given values in the above formula, we get the activation energy.
Therefore, the activation energy of the reaction is,
The initial temperature of the metal = 35 °C
<h3>Further explanation</h3>Heat can be formulated :
Q = m . c . ΔT
Q = heat, J
c = specific heat, J/g C
ΔT = temperature, °C
m = 20 g
c = 5 J/(g°C)
Q = 500 J
T₁ = 40 C
the initial temperature :
