The heat release can be calculated using the formula :
Q = m. c. delta T
Q = 107 x 4.186 x (24.70 - 21.00)
Q = 1657.2 J or 1.657 KJ
So enthalpy of the reaction = 1.657 /2
= 0.828 KJ/mol

Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change of the solution in the cup. Bomb calorimeters are used to measure combustion and other gas-producing reactions, where the reaction is observed in a strong, sealed vessel....

A total of 2.00 mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 109g of solution. The reaction caused the temperature of the solution to rise from 21.00 to 24.70 ?C. What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
Calorimetry A coffee cup calorimeter was used to measure the heat of solution - the change in enthalpy that occurs when a solid dissolves in water. A 10.0 g sample of an ionic compound with a molar mass of 130.0 g/mol was added to a sample of deionized water to produce 60.0 grams of solution. After stirring and dissolving the solid, the temperature was found to change from 25.00°C to 23.70 °C. Calculate the enthalpy of solution, AH solution, per...
Calorimetry is the measurement of heat transfer. Devices that measure the amount of heat released or absorbed during a process are called calorimeters. Coffee cup calorimeter is the simplest calorimeter and is often used to measure the heats of chemical reactions at constant pressure (also called enthalpies). This calorimeter consists of a Styrofoam cup with a plastic lid and a thermometer In today's workshop we will use calorimetry to calculate the standard molar enthalpy of reaction or the enthalpy change...
