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 ...

Inside what looks like a simple block of frozen water, quantum mechanics is quietly rewriting the rules of chemistry. New ...

Reaction rate theory is essential for understanding and simulating chemical reactions. Progress in this field has been rapid recently, and has included the development of completely new techniques for ...

The reactivity series ranks metals by how readily they react. More reactive metals displace less reactive metals from their compounds and react with water. Redox, rusting and iron - (CCEA) Oxidation ...

Researchers at the University of Illinois Urbana-Champaign have developed a new theoretical framework that could dramatically reduce the cost and complexity of predicting chemical reaction energetics ...

Molecular reactant Ball-and-stick model of carbon monoxide. The rate at which the molecule reacts with helium ions can be controlled using microwaves. (Courtesy: Benjah-bmm27) Through new experiments, ...

Six-mark questions are extended open response questions. These require longer answers than the structured questions. It is wise to plan your answer rather than rushing straight into it, otherwise you ...
