OBJECTIVE To determine the change of standard Gibbs free energy for the decomposition of sodium hydrogen carbonate (NaHCO3) from the change of standard enthalpy and the change of standard entropy. THEORY Free energy is a state function that expresses the spontaneity of a chemical process in term of enthalpy and entropy change of a system under conditions of constant temperature and volume (Hemholtz free energy) and constant temperature and pressure (Gibbs free energy). It is a quantity of non-pressure-and-volume

Experiment 16: Heat conduction Introduction In this laboratory you will study heat flow across a temperature gradient. By comparing the temperature difference across one material to the temperature difference across a second material of known thermal conductivity‚ when both are conducting heat at a steady rate‚ you will be able to calculate the thermal conductivity of the first material. You will then compare the experimental value of the calculated thermal conductivity to the known value for that

had to determine the heat exchanged when solid magnesium hydroxide is mixed with solid citric acid‚ using a coffee cup calorimeter. Given that citric acid is soluble in water is the property that makes this reaction possible. The first law of thermodynamics and Hess’s law are also present within this experiment. Knowing the difference between endothermic and exothermic reactions is also relevant. If the temperature goes down when energy is put in this means that the bonds are breaking. If the temperature

Introduction : Enthalpy is a measure of total energy of a thermodynamic system. It includes the internal energy of the system and the product of its volume multiplied by the pressure exerted on it by its surrounding. H = U + p*V Where‚ H = Enthalpy V = Volume p = Pressure U = Internal Energy The enthalpy
