Calculate the activation energy,E_a,for N₂O₅(g)→ 2 NO₂(g)+ 1/2 O₂(g) Given k (at 45.0 °C)= 5.79 × 10^-4 s^-1 and k (at 60.0 °C)= 3.83 × 10^-3 s^-1.(R = 8.314 J/K⋅mol)

Quizplus · Accepted Answer

The activation energy can be calculated using the Arrhenius equation: ln(k2/k1) = (Ea/R) * (1/T1 - 1/T2). Converting temperatures to Kelvin and substituting the given values, Ea is approximately 111 kJ/mol.
