Frequency to induce nitrogen inversion

The inversion frequency depends on the vibrational energy level, and the shape of the potential which has the form of a double well with a 'hill' in between The lowest transition has a gap of $0.7935\,...

pH at maximum concentration of a certain species (Phosphoric acid)

The fraction of the dyhydrogenphosphate, while ignoring the third ionization, is: $$x(\ce{H2PO4-})=\dfrac{K_\text{a1}\cdot [\ce{H+}]}{[\ce{H+}]^2+K_\text{a1}.[\ce{H+}] + K_\text{a1} \cdot K_\text{a2}}\...

Can increasing concentration of reactants make the RDS no longer the slowest step in the mechanism?

The rate determining step is named such because it is the slowest out of all the other steps in a reaction. By increasing the concentration, you can at most increase the rate of the overall reaction. ...
