Temperature and Rate (Section)
Understanding the high-temperature behavior of nitrogen oxides is essential for controlling pollution generated in automobile engines. The decomposition of nitric oxide (NO) to N2 and O2 is second order with a rate constant of 0.0796 M-1s-1 at 737 °C and 0.0815 M-1s-1 at 947 °C. Calculate the activation energy for the reaction.
