### How should we express concentrations and partial pressures in ΔG=-RTlnK? [duplicate]

I understand that $K$ will be dimensionless. Let's say an equilibrium involving $K_p$ and the reaction is $\ce{A -> B}$, $K_p$ will be dimensionless. If the reaction $\ce{A + B -> C}$, then ...

### Are reactive and active exactly the same terms in EAS?

I have understood the two terms as: When we say that a substituted benzene ring is reactive we mean the same thing as calling the reaction of potassium and water highly reactive. When we call a ...
For my paper, I need to find the reaction between $\ce{(CH3)2Se2}$ and $\ce{H2O2}$ and between $\ce{SeC(NH2)2}$ and $\ce{H2O2}$. The mechanism below shows how I think it goes. The reaction should ...
