FLASHCARD QUESTION
Front
What is Collision Theory?
Back
Collision Theory explains how chemical reactions occur and why reaction rates differ for different reactions. It states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.
2.
FLASHCARD QUESTION
Front
What factors affect the rate of a chemical reaction?
Back
The main factors affecting reaction rates include temperature, concentration of reactants, surface area, and the presence of catalysts or inhibitors.
3.
FLASHCARD QUESTION
Front
How does increasing temperature affect reaction rates?
Back
Increasing temperature generally increases reaction rates because it provides reactant particles with more energy, leading to more frequent and energetic collisions.
4.
FLASHCARD QUESTION
Front
What is surface area in the context of reaction rates?
Back
Surface area refers to the exposed area of a solid reactant. Increasing surface area (e.g., by crushing a solid) allows more particles to collide with reactants, increasing the reaction rate.
5.
FLASHCARD QUESTION
Front
What is concentration in a chemical reaction?
Back
Concentration refers to the amount of a substance in a given volume. Higher concentration means more particles are present, leading to more collisions and a higher reaction rate.
6.
FLASHCARD QUESTION
Front
What is the effect of a catalyst on reaction rates?
Back
A catalyst increases the rate of a reaction by providing an alternative pathway with a lower activation energy, allowing more collisions to result in a reaction.
7.
FLASHCARD QUESTION
Front
What happens to reaction rates when an inhibitor is present?
Back
An inhibitor decreases the rate of a reaction by interfering with the reactants or the catalyst, reducing the number of effective collisions.
