RATEST OF REACTION - GCSE Chemistry (AQA Topic C6)
Science Shorts・2 minutes read
Rate of reaction is influenced by factors such as concentration, pressure, surface area, and temperature, while catalysts can lower activation energy. Reversible reactions, like the Haber process, can adjust equilibrium based on changes in pressure, concentration, or temperature, as explained by Le Chatelier's principle.
Insights
- Factors influencing reaction rate encompass reactant concentration, gas pressure, surface area of solids, and temperature, with catalysts reducing activation energy to expedite reactions.
- Reversible reactions, exemplified by the Haber process, exhibit equilibrium shifts in response to alterations in pressure, concentration, or temperature, a phenomenon elucidated by Le Chatelier's principle.

Recent questions
What is rate of reaction?
Rate of reaction is the speed at which a reaction occurs, calculated as the change in quantity over time. It can be measured through experiments like reacting hydrochloric acid and sodium thiosulfate or measuring gas volume produced using a gas syringe.
What factors affect reaction rate?
Factors affecting reaction rate include increasing concentration of reactants in solution, pressure of gas reactants, surface area of solid reactants, and temperature. Catalysts can also increase reaction rates by lowering activation energy.
What are reversible reactions?
Reversible reactions, like the Haber process forming ammonia, can shift equilibrium based on changes in pressure, concentration, or temperature. Le Chatelier's principle explains how systems adjust to counteract changes in equilibrium conditions.
How do catalysts affect reaction rates?
Catalysts can increase reaction rates by lowering activation energy, making it easier for the reaction to occur. They do not get consumed in the reaction and can be reused multiple times.
What is Le Chatelier's principle?
Le Chatelier's principle explains how systems adjust to counteract changes in equilibrium conditions. If a system at equilibrium is disturbed by changes in pressure, concentration, or temperature, it will shift to minimize the effect of the disturbance and restore equilibrium.
