The rate constant is 0.049 s-1.
From the Arrhenius equation;
k = Ae^-Ea/RT
k = rate constant = ?
A = frequency factor = 4.99×10^11 s−1
Ea = Activation energy = 86.4 kJ/mol or 86400 J
R = gas constant = 8.314 J/K/mol
T = Absolute temperature = 74.0 °C + 273 = 347 K
k = 4.99 × 10^11e^- 86400/8.314 × 347
k = 0.049 s-1.
The rate constant is 0.049 s-1.
