(a)
Interpretation: The molarity of each of the elementary reactions should be determined.
Concept introduction:
Molecularity: It is defined as the number of reacting species involved in a
(b)
Interpretation: Rate equation of the reaction should be determined and decided whether it agrees with the given mechanism.
Concept introduction:
Rate law or rate equation: Rate law:
It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.
Rate constant, k: The rate constant for a chemical reaction is the proportionality term in the chemical reaction rate law which gives the relationship between the rate and the concentration of the reactant present in the chemical reaction.
(c)
Interpretation: The concentration of the product should be determined after
Concept introduction:
Rate law or rate equation: Rate law:
It is generally the rate equation that consists of the reaction rate with the concentration or the pressures of the reactants and constant parameters.
The integrated rate law for the first order is as follows:

- Which reaction mechanism assumptions are unimportant in describing simple ionic reactions between cations and anions? Why?arrow_forwardIn an aqueous solution, iodide ions are oxidized to hypoiodide ions while hypochlorite ions are reduced to chloride ions. The mechanism of this reaction has been proposed to proceed in three steps: Step 1 ClO - + H 2 O ⇋ HClO + OH- (The reaction is fast in both directions, equilibrium) Step 2 I- + HClO → HIO + Cl- (slow) Step 3 HIO + OH- → IO- + H2 O (fast) Is the proposed mechanism reasonable? Write the rate equation for formation of HIO which is implicated by the proposed mechanism.arrow_forwardWhat does "shape-selective catalysis" mean to you? Zeolites make effective shape-selective catalysts; why?arrow_forward
- If this gaseous system has an initial rate of decomposition of NOCl of 0.0025 M s-1, and the volume of the system is reduced to one third of its original value, what is the new initial rate of decomposition of NOCl? Assume the temperature remains the same.arrow_forwardStratospheric Chemistry: 6. The _________mechanismlays the foundation for current understanding of stratospheric ozone. 7. What is the importance of the ozone layer?arrow_forwardThe addition of NO accelerates the decomposition ofN2O, possibly by the following mechanism:NO(g) + N2O(g)--->N2(g) + NO2(g)2 NO2(g)--->2 NO(g) + O2(g)(a) What is the chemical equation for the overall reaction?Show how the two steps can be added to give theoverall equation. (b) Is NO serving as a catalyst or an intermediatein this reaction? (c) If experiments show thatduring the decomposition of N2O, NO2 does not accumulatein measurable quantities, does this rule out the proposedmechanism?arrow_forward
- A research group discovers a new version of happyase, which they call happyase*, that catalyzes the chemical reaction: HAPPY↽⇀SAD The researchers begin to characterize the enzyme. The researchers determined the kcat of the enzyme to be 555 s-1. In a separate experiment with [Et] at 3.2 nM and [HAPPY] at 55 µM, the researchers find that ?0 is equal to 220 nM s−1. What is the measured ?m of happyase* for its substrate HAPPY?arrow_forwardEngineers and chemists designing explosives for mining find that the reaction is occurring too quickly to be safe, yet it is not effectively fracturing the rock. Explain how the explosives and the process could be modified to decrease the reaction rate of the explosion while making the blast more effective.arrow_forwardChemistry of Fire Extinguishing Agents: Review and answer the below scenerios. a. The OSHA regulation at 29 C.F.R. §1910.162(b)(5) requires employers to provide a predischarge-employee alarm system to alert employees if a carbon dioxide concen-tration of 4% or greater is released from a fixed extinguishing system in a workplace. What is the most likely reason OSHA enacted this regulation? b. At 14 C.F.R. §121.265, FAA allows carbon dioxide to be used as a fire extinguish-ing agent onboard aircraft, provided that provisions are made to prevent harmful concentrations from entering any personnel compartment. Use Table 5.6 to deter-mine whether adverse health effects are likely to be experienced by a crew member who is confined to a compartment in which the air contains 8, carbon dioxide. c. The chemical formula of methyl bromide is CH3Br. Why does methyl bromide per-form effectively as a fire extinguishing agent? d. A potential risk of inhalation toxicity may occur to individuals that…arrow_forward
