Be sure to answer all parts. The catalytic destruction of ozone occurs via a two-step mechanism, where X can be any of several species: (1) X + O3 → XO + O2 [slow] (2) XO + O → X + O2 [fast] (a) Write the overall reaction. O3 + XO → X + 2 O2 X + O3 → XO + O2 XO + X + O3 + O → XO + X + 2 O2 O3 + O → 2 O2 (b) Write the rate law for each step (using k for the rate constant). Reaction 1: Reaction 2: k[X][O3] k[XO][O2] k[X][O2] k[XO][O3] k[XO][O2] k[X][O] k[X][O2] k[XO][O] (c) X acts as a and XO acts as a catalyst intermediate catalyst intermediate (d) High-flying aircraft release NO into the stratosphere, which catalyzes the process. When O3 and NO concentrations are 9 × 1012 molecule/cm3 and 7.4 × 109 molecule/cm3, respectively, what is the rate of O3 depletion

Which mathematical relationship should you us to convert moles of a substance into grams

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl +4h2o enter the elemental symbol. view available hint(s) is reduced

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal. b. he is determining chemical properties that are sufficient to identify the metal. c. he is determining physical properties that are insufficient to identify the metal. d. he is determining chemical properties that are insufficient to identify the metal.
