4. The high temperatures in an automobile engine cause nitrogen and oxygen to form noxious nitrogen monoxide. Use the following data on the temperature dependence of the rate constant to determine the activation energy for this reaction. 1 S-1 TICK) 1,800 2,200 7,400 2,400

Explanation / Answer

from arrhenius equation

ln(k2/k1) = Ea/R[1/T1 - 1/T2]

ln(7400/1800) = (x/8.314)((1/2200)-(1/2400))

x = actvation energy(Ea) = 310.29 kj/mol
