Interpretation:
The reason for chemist to use models to study submicroscopic matter needs to be explained.
Concept introduction:
Chemistry plays a fundamental role in science and is often intertwined with the branches of science. Chemists examine the composition of solution (or matter) along with its properties.
Answer to Problem 11SSC
Chemist generally use models to study (or examine) submicroscopic matter because submicroscopic matter is quite hard to visualize.
Explanation of Solution
Chemistry helps to know the properties, structure, composition, characteristics, and physical and chemical changes of any substances or matter. Chemists carefully explain the properties they examine in terms of quantities. All the studied details are on the level of molecule moreover with their component atoms.
Chemistry is usually portrayed at 3 different levels (or stages) of representation. These levels are symbolic, submicroscopic, and macroscopic. It combines to improve the descriptions of chemical concepts. In chemistry, models are used by chemists to explain their observations (sometimes perceptions) as they formulate (or form) theories.
It is important to examine changes in the world at a submicroscopic level because changes at this level can induce changes at macroscopic level. This scale (macroscopic) is a kind of length scale. This scale also objects or phenomena are big enough to be noticeable clearly with the naked eye. It means it is visible without any magnifying optical instruments.
Chemists carefully measure reaction rates, substance proportions, and other properties of chemicals. Chemists seek to describe the submicroscopic events (or actions) that head to macroscopic observations.

- Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NO2 (g) = N2O4(g) AGº = -5.4 kJ Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it.
