\(K_{p}\) DOES NOT PLAY THE ROLE OF THE THERMODYNAMIC EQUILIBRIUM CONSTANT, \(\boldsymbol{K}^{\boldsymbol{0}}\) : A DISCUSSED EXAMPLE ON GENERAL CHEMISTRY TEXTBOOKS’ MISREPRESENTATIONS
Equilibrium constants are important quantities when dealing with chemical equilibrium. Many first-year chemistry textbook authors do not define these terms accurately and confusion arises when reporting them. On this regard, this research discusses a common...

WHY SOLIDS AND PURE LIQUIDS ARE NOT PART OF EQUILIBRIUM EXPRESSION
The article deals with the expression of equilibrium constant of a reaction that might include a solid or a pure liquid as a reactant or a product. The typical textbook explanation for excluding terms relating to solids and pure liquid is that their concentrat...

A NEW APPROACH FOR THE SYNTHESIS OF P-ANISYL ETHYL FUMARATE: A C-9154 ANTIBIOTIC ANALOGUE
A simple, energy-efficient, and relatively quick synthetic procedure for the synthesis of p-anisyl ethyl fumarate from p-anisaldehyde has been carried out. The synthesis was started by solvent-free reduction of the aldehyde using sodium borohydrate. The se...
