Analyzing ITC Data for the Enthalpy of Binding Metal Ions to Ligands
... The enthalpy, ΔHITC, reported from the fit of titration curve represents the overall heat in the reaction cell. In order to account for all of the processes during a reaction it is recommended to analyze the data and account for each separate chemical event. Analysis may seem overwhelming at first, ...

PREPARATORY PROBLEMS (Theoretical)
... The natural tendency of any chemical reaction to proceed in a certain direction at constant temperature and pressure is determined by the sign of the Gibbs energy of the reaction, DG. This is the universal principle. If DG < 0, the reaction can proceed predominantly in the forward direction (a produ ...

What is equilibrium?
... BaSO4 is an insoluble salt that has medical applications. Doctors use it as an X-ray contrast medium (Ba absorbs more radiation than most atoms). Ba ions are poisonous and in order to make sure they are not digested, a soluble salt like Na2SO4 is given with the Ba. As SO4 ions increase the Ba ion ...

Chemical equilibrium and the kinetic theory of gases
... The partial pressures (in bar) of H2O, CO and CO2 in an equilibrium reached in a reaction vessel at 700 K were: H2O: 0.72; CO: 1.21; CO2: 2.10. Calculate the partial pressure of H2. 2 Esters, used in the food industry as flavourings, are manufactured by reacting carboxylic acids and alcohols. The e ...
