Factors Affecting Rate of Reaction

Front

What is the rate of reaction?

Back

The rate of reaction is the speed at which reactants are converted into products in a chemical reaction.

Front

What factors can affect the rate of reaction?

Back

Factors include temperature, concentration, surface area, catalysts, and inhibitors.

Front

How does temperature affect the rate of reaction?

Back

Increasing temperature generally increases the rate of reaction by providing more energy to the reactants, leading to more frequent and effective collisions.

Front

What is the role of concentration in a chemical reaction?

Back

Higher concentration of reactants increases the likelihood of collisions, thus increasing the rate of reaction.

Front

How does surface area influence the rate of reaction?

Back

A larger surface area allows more collisions between reactants, increasing the rate of reaction.

Front

What are catalysts?

Back

Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process.

Front

What are inhibitors?

Back

Inhibitors are substances that decrease the rate of a chemical reaction.

Front

Why does steel wool ignite in air?

Back

Steel wool ignites due to a chemical reaction with oxygen in the air.

Front

What is the effect of hydrogen peroxide concentration on foam production in the elephant toothpaste experiment?

Back

More hydrogen peroxide increases the size and intensity of the foam produced.

Front

What happens when baking soda and vinegar react?

Back

A chemical reaction occurs, producing carbon dioxide gas, which can cause bubbling and fizzing.
