The rate of reaction increases when reactant particles successfully collide more frequently. Temperature, reactant concentration, size of solid reactant particles (surface area) and catalysts can ...

Tell students that this reaction requires heat to get started but produces enough heat to keep reacting. You could also mention to students that a common burning candle works the same way. The wax of ...

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, ...

In chemical reactions that include a solid as one of the reactants, you can actually change the reaction rate by varying the size of the solid that reacts with the liquid or the gas. How does this ...

The measurement of the tunnelling rate in a hydrogen reaction has enabled the verification of quantum-tunnelling calculations, providing a benchmark for testing future quantum calculations.

Learn how to measure and change the rate of reaction by altering the temperature, concentration and surface area or through the use of a catalyst. ... (CCEA) Typical rate of reaction experiments.
