Q: Two-state binding in surface plasmon resonance (SPR): how to get affinity from the four kinetic parameters

Surface plasmon resonance (SPR) SPR is a widely used technique to measure biomolecular interactions. My question has to do with the models (i.e. equations) used to fit parameters to SPR data, and the relation between binding affinity and kinetics. My question is less theoretical and more practi...

@Mithoron Hi can you help me with a doubt?

A: How to calculate n factor for salts in this reaction?

$$\ce{2 Na3PO4 + 3 BaCl2 -> 6 NaCl + Ba3(PO4)2}$$ Now this is clearly evident that dividing whole equation by 2 we get 1 mole of $\ce{Na3PO4}$ and at the right hand side 3 moles of $\ce{NaCl}.$ Therefore, 1 mole of phosphate ion is replaced by 3 moles of $\ce{Cl-}$ ion. Hence $n\text{-factor} = 3...

it is isn't true that n factor is equal to total positive charge in an compound if it is not in redox reaction as said in the answer right?

Also how do we actually calculate n factor?

I am tempted to flag all these "n factor" questions as off-topic because n factors are not used in actual chemistry.

NOTE Book

Yes i read that n factor isn't much useful now but it is a part of syllabus that is why I am doing it :(

Q: Why do water and ice and have the same vapor pressure at 0 °C?

I've seen that at the melting point of water, 0 °C at 1 atm, water and ice have the same vapor pressure. But I can't figure out, intuitively, why this is the case. The enthalpy of sublimation of ice at 0 °C is greater than the enthalpy of vaporization of water, so it seems like it would be "easier"...
