### Say I have the following simple reaction


$
 \ce{HCl(aq) + NaOH(aq) \rightarrow NaCl(aq) + H2O(l)}
$


Does there exist a calculation which gives the ideal temperature for this reaction to occur at?


### Background


I used this example as it was the easiest one I could think of from the top of my head but I mean this generally.


I tried looking this up but could only find calculations to do with how much heat is released.


### Edit


Ideal meaning the point in temperature where the reaction will give the greatest yield of products. Kind of reminds me of enzymes the optimum temperature.


Like one of the commentators mentioned the haber process, **the temperature at which the equilibrium shifts mostly to the right**, or the minimum temperature required for the reaction to get going.


### Actual question


Is there an equation which calculates the optimum/shifts equilibrium mostly to the right temperature or is it just empirical? I mean a general equation which might apply to most reactions, if there is such a thing?


Apologies for being vague.




Anytime when asking for ideal, optimal or the best, the one who asks must provide criteria, how the ideality, optimality or being the best is evaluated, as it is highly subjective criteria.


In reaction context, one of possible criteria is the maximal reaction quotient achieved at given reaction conditions, together with minimal expenses. This makes sense for slow enough reactions, what is not the case of strong acid + base neutralisation.


The typical textbook case for optimization is catalyzed Haber-Bosch synthesis of ammonia:


$$\ce{3 H2(g) + N2(g) <=> 2 NH3(g)}$$


There are 4 major factors:


1. Increased temperature speeds up the reaction.
2. Increased pressure shifts equilibrium in favour of the product.
3. Increased temperature shifts the equilibrium constant in favour of the reactants.
4. Increased cost for higher pressure and temperature.


The reaction is performed as gases pass the solid state catalyst, ammonia is separated and remaining reactants are by loopback returned to react.


The pressure is kept as high as technologically reasonable. But there are higher time and operational expenses (device cost, energy spent) for higher pressure.


The major parameter to optimize is temperature:


* If too low, reaction is limited kinetically, only small fraction would react, in spite of the equilibrium position.
* If too high, reactants react fast, but just small fraction due low equilibrium constant value. And there is higher energy cost.


From evaluation of the reaction kinetics and thermodynamics, technological and cost aspects, the optimal pressure and temperature is determined.
