Answer:
the proton
Explanation:
Inside an atom there are neutrons which have a neutral charge (no charge) and protons which have a positive charge. Outside an atom there are electrons those have a negative charge.
<u>Answer:</u> The activation energy for the reaction is 40.143 kJ/mol
<u>Explanation:</u>
To calculate activation energy of the reaction, we use Arrhenius equation for two different temperatures, which is:
where,
= equilibrium constant at 317 K =
= equilibrium constant at 278 K =
= Activation energy = ?
R = Gas constant = 8.314 J/mol K
= initial temperature = 278 K
= final temperature = 317 K
Putting values in above equation, we get:
Hence, the activation energy for the reaction is 40.143 kJ/mol
