In the troposphere carbon monoxide and nitrogen dioxide undergo the following reaction: NO2(g) CO(g): NO(g) CO2(g) Experimentally, the rate law for the reaction is second order in NO2(g), and NO3(g) has been identified as an intermediate in this reaction. Construct a reaction mechanism that is consistent with these experimental observations.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
