Why does the temperature drop once the reaction reaches the stoichiometric point?

In can occur if the reaction in question in exothermic. After the stoichiometric point , there is no reactant left to react. No reaction occurs and no heat is evolved and as a result temperature drops.

∙ 9y agoThe temperature drops when the reation reaches the stoichiometric point (equivalence point) because the amounts of the titrant and the analyte have completely reacted.

The altitude at which rising air reaches the dew point temperature is the?
Lifting Condensation Level
Clouds begin to form when water vapor in the air reaches the correct?
Clouds begin to form when water vapor reaches the correct: altitude, dew point, and temperature.
When water is heated the temperature eventually reaches a constant value and forms a plateau on the graph what does the plateau indicate?
The boiling point.
When air mass cools when will water condense?

When the temperature reaches the correct temperature (boiling point).
What is true about the amounts of H and OH at the stoichiometric point in a titration of a strong acid with a strong base?
'Stoichiometric' means equal amounts according to the balanced reaction. So at that point you have only water where H+ and OH- conc.'s are equal (1.0*10-7)
What is the stoichiometric point of a titration called?

What is the optimal point mean?
In biochemical reaction, an optimal point is the highest point that the temperature and reach in a reaction without causing damages to the enzymes.
What is the equivalence point of titration?
The equivalence point, or stoichiometric point, of a chemical reaction is the point at which an added titrant is stoichiometrically equal to the number of moles of substance (known as analyte) present in the sample: the smallest amount of titrant that is sufficient to fully neutralize or react with the analyte.
