Explain why transition metal complexes are coloured?

In a complex transition metal ion, the electric field produced by the lone pairs on ligands when they interact with the central metal ion causes the d orbitals to split into two sub levels. As the dx...

Calculate ΔG (in kJ/mol) of the reaction of molecular oxygen and carbon monoxide to produce carbon dioxide. The reaction occurs at 25°C. ΔH = -566 kJ/mol, ΔS = -173 J/K. Based on the result, determine the spontaneity of the reaction.

First we need to write down the chemical equation and balance it: O2 + 2CO -> 2CO2 Given the data, we can calculate ΔG using the following formula: ΔG = ΔH - TΔS However, before w...
