Temperature, reactant concentration, size of solid reactant particles (surface area) and catalysts can all affect the reaction rate. Part of Combined Science Further chemical reactions, rates and ...

Identical concentrations of solutions A and B at three different temperatures (hot, room, and cold) are mixed. The different lengths of time needed to achieve the starch/iodine complex shows the ...

K910: Effect of Concentration and Temperature on Rates – Iodine Clock; K912: Effect of Concentration on Rate Bleach and Green Food Coloring; K918: Iodine Clock Class Activity; K925: Hot Packs vs ...

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 of reaction increases Compared to a reaction with a reactant at a low concentration (if a solution), the graph line for the same reaction but at a higher concentration: has a steeper ...
