SOLVED: Peroxide forms nitrogen gas and water vapor. The oxidation of hydrazine, N2H4, by hydrogen at 25Â°C forms hydrazine, hydrogen peroxide, and water. The standard enthalpies of formation, Î”HÂ°f (kJ mol^-1), for hydrazine, hydrogen peroxide, and water are 268.8, 187.8, and -241.8, respectively. What is the temperature at which 1 dm^3 of water is heated by 10.0 g of hydrogen peroxide during the oxidation of hydrazine? [9.5]

SOLVED:Hydrazine (H2 NNH2), hydrogen peroxide (HOOH), and water (H2 O) all have exceptionally high surface tensions compared with other substances of comparable molecular weights. (a) Draw the Lewis structures for these three compounds. (b) What structural property do these substances have in common, and how might that account for the high surface tensions?

A proposed mechanism for the decomposition of hydrogen peroxide consists of three elementary steps: (1) H2O2(g) → 2 OH(g) (2) H2 O2(g) OH(g) →H2 O(g) HO2(g) (3) HO2(g) OH(g) →H2 O(g) O2(g) If the rate law for the reaction is first order in H2 O2, which step in the mechanism is the rate-determining step? | Numerade

The decomposition of hydrogen peroxide was studied, and the following data were obtained at a particular temperature: Time (s) [H2O2](mol / L) 0 1.00 120 ± 1 0.91 300 ± 1 0.78 600 ± 1 0.59 1200 ± 1 0.37 1800 ± 1 0.22 2400 ± 1 0.13 3000 ± 1 0.082 3600 ± 1 0.050 Assuming that Rate =-(Δ[H2 O2])/(Δt) determine the rate law, the integrated rate law, and the value of the rate constant. Calculate [H2 O2] at 4000 . s
