There are two O-H bonds in H2O, multiplying O-H bond energy by two accounts for all the bonds present in water. What is the bond enthalpy unit? The bond enthalpy, also known as the bond energy, is the energy that is stored in chemical bonds. It has units in energy per mole. The...

PEARSON 1 recently pointed out that Pauling's bond energy equation does not give reasonable values of the enthalpy changes for a series of reactions and he has also stressed a number of pitfalls of Pauling's electronegativities. The principle of soft and hard acids and bases (SHAB), on the...
Start with the equation in (b) and show that for the mixing of components to form a mole of solution, the ideal Gibbs free energy change, ideal enthalpy change, and ideal entropy change are given by ΔmixGmid=RT∑ixiln xi, ΔmixHmid=0,and ΔmixSmid=−R∑ixiln xi, P11.7 St...

The fundamental equation for G' is the basis for deriving the expression for the apparent equilibrium constant K' for a biochemical reaction, the standard transformed Gibbs energy of formation DELTA(f)G'(O), and the standard transformed enthalpy of formation DELTA(f)H'(O) of a biochemical ...
For a gas, the relationship between volume and pressure (at constant mass and temperature) can be expressed mathematically as follows. P∝ (1/V) Where P is the pressure exerted by the gas and V is the volume occupied by it. This proportionality can be converted into an equation by adding...
The equations for the change in glass transition temperature with stretching are derived to test the criteria for glass transition, i.e., the iso-free volume, the iso-configurational entropy, and the iso-configurational energy assumptions. It was found that the second assumption explains the ...
A thermochemical equation is a balanced chemical equation that displays the magnitude of the enthalpy value associated with the process. An enthalpy value with a positive sign means the equation has been written for an endothermic process, whereas a negative sign suggests an exothermic process.What...
