The kinetic molecular theory can be used to explain each of the experimentally determined gas laws. The Link Between P and n. The pressure of a gas results from collisions between the gas particles and the walls of the container.
Molecular orbital theory is concerned with the combination of atomic orbitals to form new molecular orbitals. These new orbitals arise from the linear combination of atomic orbitals to form bonding and antibonding orbitals. The bonding orbitals are at a lower energy than the antibonding orbitals, so they are the first to fill up. By figuring out the molecular orbitals, it is easy to calculate bond order.
