2024 ESL Factors Affecting Reaction Rates

Front

What does the Law of Conservation of Mass state?

Back

The Law of Conservation of Mass states that the amounts of atoms in the reactants and the products stay the same during a chemical reaction.

Front

How does increasing surface area affect reaction rates?

Back

Increasing surface area increases the frequency of collisions among particles, leading to a higher reaction rate.

Front

Can chemical reactions occur at different speeds?

Back

Yes, chemical reactions can occur quickly or slowly depending on various factors.

Front

How many carbon atoms are in the chemical formula 3CO₂?

Back

There are 3 carbon atoms in the chemical formula 3CO₂.

Front

What effect does increasing pressure have on the rate of reaction in gases?

Back

Increasing pressure increases the rate of reaction by increasing the frequency of collisions among gas particles.

Front

What is a reactant?

Back

A reactant is a substance that undergoes a chemical change in a reaction.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

What role do catalysts play in chemical reactions?

Back

Catalysts speed up chemical reactions without being consumed in the process.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does temperature affect reaction rates?

Back

Increasing temperature generally increases reaction rates by providing more energy to the particles.
