reaction 2NO + O [8] 2 −−→ 2NO2

, write the rate law for the formation of NO2

using the following mechanistic proposal and the steady state approximation. Be sure to

eliminate intermediates from the rate expression. Do not make any assumptions about

fast or slow steps (i.e. do not simplify your expression by assuming anything about the

relative magnitude of κ
