why does lithium fluoride have a higher lattice energy than lithium iodide?

Based on my knowledge, lattice energy is proportional to the multiplcation of the charge of the ions, divided by the sum of the radius of ions, as follows. Since iodide has a larger radius than fluoride, by this equation lithium iodide would have a less exothermic lattice energy (lower lattice energy). However, I also learned […]

Thermodynamics of chemical reactions “at constant pressure”

Chemical reactions occur at constant temperature and pressure. Consider a gaseous, equilibrium reaction: $\ce{2NO2(g) <=> N2O4(g)}$. Most questions/textbooks formulate such questions by stating: The reaction happens at ($T$) temperature and ($P$) pressure. This gives the impression that the surrounding Temperature and pressure are constant. The first confusion that then arises is: For thermodynamic quantities such […]

Is the width of a Soxhlet Condenser Inherent to its Function?

Soxhlet extractors are often coupled to a specifically designed condenser with a very large lower joint. Is this inherent to it’s function as a condenser in the apparatus or only because the Soxhlet Extractor part underneath it needs a big upper joint to get stuff in and out? In other words, is there any drawback […]

Pyridine synthesis by tin(II) chloride reduction of 5-nitronorbornene

What is the reaction mechanism here? I guess the $\ce{SnCl2}$ reduces $\ce{NO2}$ to $\ce{NH2}$ but then what happens?

Using Quantum Mechanics to understand the size of an atom

What is the quantum mechanical approach of explaining the fact that: "The size of the atom increases when a new shell is filled" ??? I mean how do you explain this phenomenon using ideas of quantum mechanics….besides classical ideas…???
