Using the now-decommissioned Summit supercomputer, researchers at the Department of Energy's Oak Ridge National Laboratory ...

Discusses the factors influencing chemical reaction rates and equilibrium. It explains how different reactions occur at varying rates due to factors such as the nature of reactants, surface area ...

The rate at which the molecule reacts with helium ions can be controlled using microwaves. (Courtesy: Benjah-bmm27) Through new experiments, researchers in Switzerland have tested models of how ...

Measuring rates of reactions. When a chemical reaction occurs, chemists can measure how fast it is occurring by tracking the change of reactant s into products. A rate is a measure of how one quantity ...

Understanding chemical reaction rate and the factors that affect it is essential to the production of chemicals for society. Chemists use scientific equipment and apparatus to measure rates of ...

1. Introduction. Chemistry is often regarded as a difficult subject, an observation which sometimes repels learners from learning this subject. This is because Chemistry includes many complicated and ...

In chemical solutions, the products of catalytic reactions can occupy different volumes compared to the reactants and thus give rise to local density variations in the fluid. These density variations ...

The chemical reaction that happens in a light stick is slower when cold. Do you think that starting with warmer reactants increases the rate of other chemical reactions? Why? It is reasonable to think ...

What clues did you have that a chemical reaction occurred in this activity?Bubbling. Tell students that a change in temperature is also a sign that a chemical reaction may be occurring. Endothermic ...
