Exercise 1 Benzene adsorbed on graphite is found to obey the Langmuir isotherm to a good approximation. At a pressure of 1.00 Torr, the volume of benzene adsorbed on a sample of graphite was found to be 4.2 mm³ at STP; AT 3.00 Torr, it was 8.5 mm³. Assume benzene to occupy 30 A2 and estimate the surface area of graphite. [Answer: 0.140 m²]
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
