(mathematics, chemistry) The use of computation to predict the structure, properties and reactions of molecules

C60 molecule with isosurface of ground-state electron density as calculated with density functional theory

(mathematics, chemistry) The use of computation to predict the structure, properties and reactions of molecules

Computational chemistry can help predict values like activation energy from catalysis. The presence of the catalyst opens a different reaction pathway (shown in red) with lower activation energy. The final result and the overall thermodynamics are the same.
