Study Notes
Reactions and Rate Laws
- Nitrous oxide decomposes into nitrogen and oxygen per the reaction: 2N2O(g) → 2N2(g) + O2(g).
- Concentration versus time plot indicates green curve associates with N2O, while blue curve associates with N2.
Dinitrogen Pentoxide Decomposition
- Dinitrogen pentoxide (N2O5) decomposes to nitrogen dioxide (NO2) and nitrogen trioxide (NO3): N2O5(g) → NO2(g) + NO3(g).
- Average rates of reaction (molecules/(cm³ × s)) calculated:
- Rate 1: 4.9 x 10^10
- Rate 2: 3.1 x 10^10
- Rate 3: 2.0 x 10^10
- Rate 4: 1.0 x 10^10
Hydrogen Gas Reaction
- Reaction: 2H2(g) + 2NO(g) → 2H2O(g) + N2(g).
- Initial reaction rates obtained at 1500°C for varying concentrations of H2 and NO.
- Rate law derived: Rate = k[H2]^2[NO].
- Rate constant at 1500°C: 6.36 M^-1s^-1.
Organic Reaction Rate Law
- For reaction between organic molecule A and NaSH:
- Tripling [A] triples the rate.
- Doubling [A] while cutting [NaSH] reduces the rate.
- Halving [A] and quadrupling [NaSH] doubles the rate.
- Derived rate law: Rate = k[A][NaSH].
Atmospheric Chemistry and Hydroperoxyl Radical
- Hydroperoxyl radical (HO2) decomposes into H2O2 and O2.
- Rate law determined: Rate = k[HO2].
- Rate constant at 298 K: 0.854 µs^-1.
Second Order Reactions
- Reaction: 2A → A2 determined to be second order with rate constant k = 0.0265 M^-1min^-1.
- Initial concentration of A = 3.25 M; concentration after 180 min = 0.197 M.
Dimerization of ClO
- Reaction: 2CIO(g) → CI2O2.
- Rate constant (k) at 350 K: 6.75 x 10^-6 cm³/molecules × s.
- Half-life at 350 K: 0.712 s.
