Concept introduction:

Electronic configuration:

The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

(1) Electrons occupy in the lowest energy orbitals. The increasing order of orbital energy is $s, p, d and f$ . The lowest energy orbital is $1s$ . The order of energy of the orbital for the for the first three period is given below,
$1s, 2s, 2p, 3s, and 3p$ .

(2) The orbital which is closer to the nucleus has lower energy, therefore the 2s is lower in energy than 3s. Accordingly $2s$ is lower in energy than $2p and 4s$ is lower in energy than $3d$ .

(3) In general, the orbitals can hold maximum of two electrons, the two electrons must have opposite spin.

The subshell ordering by aufbau principle is given below, $1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s, ...$

Each shell contains only a fixed number of electrons. The first shell contains two electrons, the second shell contains eight (2 + 6) electrons, the third shell contains 18 (2 + 6 + 10), fourth shell contains (2 + 6 + 10 + 14 ) and so on.

1. (10 points) Pulverized coal pellets, which may be ° approximated as carbon spheres of radius r = 1 mm, are burned in a pure oxygen atmosphere at 1450 K and 1 atm. Oxygen is transferred to the particle surface by diffusion, where it is consumed in the reaction C + O₂ →> CO₂. The reaction rate is first order and of the form No2 = k₁C₁₂(r), where k₁ = 0.1 m/s. Neglecting changes in r, determine the steady-state O₂ molar consumption rate in kmol/s. At 1450 K, the binary diffusion coefficient for O2 and CO2 is 1.71 x 10ª m²/s.

2. (20 points) Consider combustion of hydrogen gas in a mixture of hydrogen and oxygen adjacent to the metal wall of a combustion chamber. Combustion occurs at constant temperature and pressure according to the chemical reaction 2H₂+ O₂→ 2H₂O. Measurements under steady-state conditions at 10 mm from the wall indicate that the molar concentrations of hydrogen, oxygen, and water vapor are 0.10, 0.10, and 0.20 kmol/m³, respectively. The generation rate of water vapor is 0.96x102 kmol/m³s throughout the region of interest. The binary diffusion coefficient for each of the species (H, O̟, and H₂O) in the remaining species is 0.6 X 10-5 m²/s.
