Answer:
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.

Answer: The activation energy for the reaction is 209 kJ
Explanation:
According to the Arrhenius equation,
or,
where,
= rate constant at
=
= rate constant at
=
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get
:
Therefore, the activation energy for the reaction is 209 kJ
