Question

if temperature increases are the reactions endo Prelab for Expt 11 1. What is the primary objective of this experiment? All three reactions that you will carry out in this experiment will result in a temperature increase. Are the reactions endothermic or exothermic? Explain 2. pted ??'nn for Reaction 2, Use the H°1 values from the t ng the information found in the introduction of this experiment, calcula eat (in J) of the reaction if 50.0 ml of HCl is added to 50.0 mL of NaOh coffee-cup calorimeter. The initial temperature for both solutions is 25.3 the final temperature is determined to be 37.6C. c9.14

Explanation / Answer

2) When heat is given out in any reaction it is termed as exothermic reaction and when heat is absorbed during a course of reaction it is termed as endothermic reaction. Since, the given reaction results in an increase in temperature during the course of reaction, it indicates that heat is given out when the reactant reacts, thus the reactions are exothermic in nature.
