The relation between activation energy, rate constant and temperature is given by Arrhenius equation
Arrhenius equation is
ln (K2/ K1) = Ea / R (1/T1- 1/T2)
K2 = 1×10−3s−1 T2 = 525 ∘C = 798 K
K1 = 1×10−4s−1 T1 = 485 ∘c = 758 K
Ea = ?
R = gas constant = 8.314 J / mol K
ln (K2/ K1) = ln (10^-3 / 10^-4) = 2.303 = Ea /8 .314 (1/758 - 1 / 798)
2.303 = Ea / 8.314 (0.00132 - 0.00125)
Ea = 2.303 X 8.314 / (0.00132 - 0.00125) = 273530.6 J / mole
Ea = activation energy = 273.531 kJ / mole
