A physical phenomenon called quantum tunnelling is rare in chemical reactions, making it difficult to study theoretically and experimentally. The measurement of the tunnelling rate in a hydrogen ...

The rate of a chemical reaction is a measure of how fast the reactants are being used up and how fast the products are being made. Reactions in which a gas is produced can be used to monitor the rate.
