Why do we use the limiting reactant data to calculate ∆H? Why might it be important to know ∆H prior to running a reaction?
Homework Answers
ANSWER:-
in a chemical reaction, the limiting reagent is the reactant that determines how much of the products are made.
and it is important for one reason, to know how much heat you have to remove or add to maintain constant temperature.
it is very important to maintain temperature prior to the reaction so we have to maintain ∆H value , if we don't do so than reaction will not complete successfully .

2. Demonstrate through mole calculations that iodate was indeed the limiting reactant in the production of triiodide in Part I – Goal 3 (titration) of this study. You have three reactants to consider KI, iodate, and H+. Assume that 1/4 teaspoon of KI is approximately 1 g. Im not sure how to find the products to do the work with this equation. Also, how do I know how the coefficients of the reactants. A molarity of 0.0108 was used for...
