12.1/2/3 Introduction to Rate

Front

What is the name given to a catalyst in the human body?

Back

Enzyme

Front

When surface area is increased, what happens to the rate of reaction?

Back

Increases, because there are MORE possible sites for correct collisions.

Front

What does the gradient tangent on a reaction rate graph represent?

Back

Rate of reaction at a specific time.

Front

What will happen to the rate of product formation if the concentration of reactants is increased?

Back

Products will form faster.

Front

What does concentration refer to in a solution?

Back

How much particles are dissolved in a solution.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed.

Front

How does temperature affect the rate of reaction?

Back

Increasing temperature generally increases the rate of reaction.

Front

What is the relationship between particle size and reaction rate?

Back

Smaller particle size increases the rate of reaction.

Front

What is the effect of stirring on the rate of reaction?

Back

Stirring can increase the rate of reaction by distributing reactants more evenly.

Front

Define surface area in the context of reactions.

Back

The total area of the surface of a solid reactant that is exposed to the other reactants.
