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,
Explanation:
Reaction equation for this reaction is as follows.
It is given that = 0.0118.
According to the ICE table,
Initial: 0.86 0.86 0 0
Change: -x -x +x +x
Equilibrium: 0.86 - x 0.86 - x x x
Hence, value of will be calculated as follows.
0.0118 =
x = 0.084 atm
Thus, we can conclude that is 0.084 atm.
