Q: Why do chemists like to work with common logarithms (base 10)?

BuraianIn my understanding, every operation we do in $\log_{10}$ can be done in the natural logarithm itself and it should be better because mathematical integrals naturally give out expressions involving the natural logarithm function. However, it seems that in my chemistry books there are elaborate sc...

Q: Considering Gibbs energy or electrode potential to find disproportionation tendency

TRCThe following data was given (without the asterisks and footnote) asking us to find the oxidation states that would have a tendency to disproportionate - By tendency to disproportionate, I understood that the disproportionation reaction must be spontaneous, implying change in Gibbs free energy s...

Q: What is the IUPAC name of perchloroisobutane?

Sukessh Velusamy What is the IUPAC name of $\ce{(CCl3)3CCl}?$ The answer I got was 1,1,1,2,3,3,3-heptachloro-2-(trichloromethyl)propane. But when I looked up the question online, most sources say the answer is 2-(trichloromethyl)-1,1,1,2,3,3,3-heptachloropropane, even though ‘chloro’ comes before ‘trichlorometh...

Q: Is standard change in activation Gibbs free energy indepedent of pressure?

AntonFor a chemical reaction the activation volume is defined as: $$Δ^{\ddagger}V={V^\ddagger}-V$$ where both $V^\ddagger$ and $V$ refer to standard states (I have omitted the symbol for simplicity). One can calculate activation volume by taking the partial derivative with respect to pressure of $$Δ^{...

Q: Why is standard state useful?

AntonIn order to calculate the equilibrium constant we must know the value of $\Delta_\mathrm{r}G^{\circ}$ (which is a function of $T$) so we can calculate $K$ as: $$K = \exp\left(-\frac{\Delta_\mathrm{r}G^{\circ}}{RT}\right)$$ Now if the standard state is changed (for example from $\pu{1 atm}$ to $\p...
