Bear with me, please. My knowledge of Gibbs, bond formation, entropy and enthalpy is weak, and I think they're needed to figure this out.
Suppose I have "some" sulfuric acid and "some" salt, and I mix them. At least two reactions are possible:
(I have intentionally left out coefficients) the stochiochemistry of the inputs does not (necessarily) determine the outcome: an excess of one reagent might pass unreacted through to the end of the equation, leaving either one a legitimate outcome.
So we have several forces warring with one another:
So two questions:
Thanks kindly for any insight.

H2SO4 + NaCl -> Na2SO4 + HCl
H2SO4 + NaCl -> NaHSO4 + HCl
H2SO4 + NaCl -> NaHSO4 + HCl
(I have intentionally left out coefficients) the stochiochemistry of the inputs does not (necessarily) determine the outcome: an excess of one reagent might pass unreacted through to the end of the equation, leaving either one a legitimate outcome.
So we have several forces warring with one another:
1) The stochiochemistry of the reactants
2) Entropy
3) The "energy level" of the sulfate vs bisulfate
4) The input energy (heat)
2) Entropy
3) The "energy level" of the sulfate vs bisulfate
4) The input energy (heat)
So two questions:
1) How do I know what product will be favored under what conditions? vs
2) How do I arrange conditions such that a particular product will be favored?

Thanks kindly for any insight.
