FO $16$: Predict the equilibrium position of acid$-$base reactions using thermodynamic stability of reactants and products.

Imagine that you mixed equal moles of acid and base in a non$-$reacting solvent, so that this equilibrium has been established.

$($a$)$ List the acids and bases that

$($b$)$ Draw a reaction$-$energy diagram using the axes shown, are present in the solution: and label all reactants and products on the diagram.
