What are Van Der Waals dispersion forces?

Van der Waals forces are a form of intermolecular (between molecules) force. A covalent bond is created by a shared pair of electons. (For example two chlorine atoms will share 2 electrons to form a Cl 2 mol...

How do I calculate the Gibbs free energy change for a reaction when given the entropy change, enthalpy change and the reaction conditions>

deltaG= Gibbs free energy deltaG=deltaH - TdeltaS If deltaH= 150 kJ/mol and deltaS=2.1 J/mol we must first convert the deltaS into kJ/mol, this is done by multiplying by 10 -3 . So deltaS= 2.1 x 10 -3 kJ/mol...
