Answer:
The question has some details missing which I have shown in the attached file.
Explanation:
The concept of arrehenius equation is used to calculate the activation energy.
- Given T1 = 141.0 degree celsius = 414K and K1 = 3.3 x 10^8
- T2 = 77 degree celsius = 350K and k2 = 1.1 x 10^8
- R = 8.314
- from Arrehenius equation;
- ln(k2/k1) = -Ea/R [1/T2 - 1/T1]
- Plugging the values ;
- ln(1.1/3.3) = -Ea/8.314 [ 1/350 - 1/414]
- Ea = 20.679KJ/mol = activation energy for this reaction
