Chemistry Reaction rate/Reversible reaction

Front

What is a catalyst?

Back

A substance that increases the rate of a reaction without being used up during the reaction.

Front

What is chemical kinetics?

Back

The study of how fast chemical reactions occur.

Front

What is a reversible reaction?

Back

A reaction going forward and backward at the same time.

Front

What factors increase the rate of a reaction?

Back

Increasing temperature, increasing concentration, increasing surface area, and all of these.

Front

What does the symbol ⇌ indicate?

Back

That a reaction is reversible.

Front

What is the effect of temperature on reaction rate?

Back

Increasing temperature generally increases the reaction rate.

Front

How does concentration affect reaction rate?

Back

Increasing concentration of reactants typically increases the reaction rate.

Front

What is the role of surface area in chemical reactions?

Back

Increasing surface area allows more collisions between reactants, increasing the reaction rate.

Front

What is an example of a reversible reaction?

Back

The synthesis of ammonia (N2 + 3H2 ⇌ 2NH3).

Front

What is the difference between a reactant and a product?

Back

Reactants are substances that start a chemical reaction, while products are substances formed as a result of the reaction.
