What is the dissociation constant of the reaction HCl <-> H(+) + Cl(-) at 25°C?

Is it pK=-8 or pK=-6.3? From the current definition of pH and from the electroneutrality is measured and calculated the value of K=10^8: If we measure pH and if we know the total amount of...

Are the values 1mol/kg or 1mol/L reasonable for molality or molarity standard state of each solution?

A chemical activity can be defined as a=γ*x, a=γ*m/mo or a=γ*c/co, where γ is activity coefficient, x is mole fraction in mol/mol, m is molality in mol/kg, c is molarity in mol/L. The...

Can a forward reaction rate of chemical reaction be calculated from Gibb's energies of substrates?

The idea is to divide the equation of equilibrated chemical reaction into forward and backward part. The equation dG = - T R ln(kf/kb) into dGp - dGs = T R ln(kb/C) - T R ln(kf/C), where dG is...
