The gaseous compound dinitrogen pentoxide (N₂O₅) decomposes in air to yield nitrogen dioxide gas (NO₂) andoxygen gas (O₂). If we can determine the rate of this decomposition, we can also determine the concentration ofdinitrogen pentoxide in a given sample at any point in time. This reaction is typically conducted in an apparatus such as the following, in which the water bath is used to control the temperature surrounding the dinitrogen pentoxide gas.
In your analysis, you’ll examine data collected during the decomposition of 0.25 M dinitrogen pentoxide gas. Theconcentrations of dinitrogen pentoxide, nitrogen dioxide, and oxygen were measured at eight different time points at normal atmospheric pressure and a temperature of 45°C.
1. Write a balanced equation for this decomposition reaction, including phase notations.
Explain why we don't use the balance chemical equation to determine rate law
Kinetics Broadly speaking, the factors that influence chemical reaction rates may be summarised as follows.Chemical nature of reactants (e.g. is the chemical reaction thermodynamically “downhill” so that it can occur spontaneously at all?)Reactant Concentration (or pressure for a gas)Physical state of reactants (e.g. phase, or surface area of solids)Presence of catalystTemperature
For each of the following observations, which one of the five factors is most important, and briefly explain how/why that is the case.
(a) The ability to sustain aerobic exercise is limited by the amount of haemoglobin in the blood.
(b) Non-starch polysaccharides are large complex carbohydrates, and an important source of dietary fibre. Their chemical energy content is similar to other carbohydrates like sucrose. These molecules do not undergo respiration via by human digestion, but some bacteria have specialised proteins that can process non-starch polysaccharides.
(c) Potato is made edible by cooking it…
