The difference in potential energy U between two configurations is given by the work done by external forces to change the system from one configuration to the other (this is done infinitesimally slowly so that there is no change in the kinetic energy). If U is positive then the new ...

Dissociation of a Diatomic Gas
... Let us consider the following simple model for a diatomic gas: a diatomic molecule consists of a pair of point-like atoms, each of mass m, separated by a rigid rod of length a. The rigid rod corresponds to the chemical bond, which requires an energy to break. Now, at any finite temperature T , we ...

... Are they, H2O2 and 2OH, the same substance? __No___ Explain your answer: No they are not the same substance even though they have the same amount and type of atoms. H2O2 is one molecule of Hydrogen Peroxide that has all of its atoms bonded together. Whereas, 2OH is two molecules of OH bonded togethe ...

... (a) Both NO2 and N2O4 are gases, since N2O4 is the larger molecule, it is expected to have the higher standard entropy. So value for N2O4 = 304.38 J K-1 mol-1 whereas for NO2 it is 240.04 J K-1 mol-1 (b) Gases have higher entropies than solids So value for I2(g) = 260.69 J K-1 mol-1 whereas for I2(s ...
