AI Thread Summary
The discussion focuses on the exceptions to the Aufbau principle, specifically regarding the electron configurations of cobalt (Co) and molybdenum (Mo). It highlights that these elements deviate from the expected configurations due to stability considerations, often involving half-filled or fully filled d subshells. Participants are encouraged to research the Aufbau principle and examine the specific electron configurations of Co and Mo to understand these exceptions better. The conversation emphasizes the importance of stability in determining electron arrangements. Understanding these deviations is crucial for grasping advanced concepts in chemistry.

Do you know what Aufbau principle is? Read about it in your book, you may also consult wikipedia. Then take a look at Co and Mo electron configuration - are these expected when applying Aufbau principle?

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
