Which type of reaction is often faster?

Reactions involving liquids and solids

Which type of reaction is slower?

Heterogeneous reactions that involve solids

What happens to the rate of most reactions if the reactant concentration is increased?

The reaction rate remains the same.

Why do reactions proceed faster when the reactant concentration is increased?

There are more molecules, so more collisions are possible.

There are fewer molecules, so fewer collisions are possible.

How does increasing the surface area of a reactant affect the reaction rate?

The reaction rate remains the same.

What is the effect of higher temperatures on the number of collisions between molecules?

The number of collisions increases.

The number of collisions decreases.

The number of collisions remains the same.

The number of collisions fluctuates.

What is the role of a catalyst in a chemical reaction?

It increases the rate of reaction without being consumed.

It decreases the rate of reaction and is consumed.

It appears in the overall balanced equation.

It does not affect the kinds of collisions.

How do catalysts affect the kinds of collisions in a reaction?

They change the mechanism of the reaction.

They do not affect the collisions.

They decrease the number of collisions.

They increase the energy of collisions.

In which types of reactions are catalysts critical?

In both biological (enzyme) and industrial reactions.

In neither biological nor industrial reactions.

What types of rates are measured to understand a reaction?

Average and instantaneous rates

What do the balls changing from red to blue illustrate in the context of the reaction?

The progress of a reaction over time

The temperature change over time

What is the chemical equation for the reaction described in the document?

C₄H₉Cl(aq) + H₂O(l) → C₄H₉OH(aq) + HCl(aq)

C₄H₉Cl(aq) + H₂O(l) → C₄H₉OH(aq) + H₂(aq)

C₄H₉Cl(aq) + H₂O(l) → C₄H₉OH(aq) + Cl₂(aq)

C₄H₉Cl(aq) + H₂O(l) → C₄H₉OH(aq) + O₂(aq)

Why is it difficult to measure concentration at time zero?

Because a time (t) is chosen during the course of reaction to assess the reaction

Because the reaction has not started

Because the concentration is too high

Because the concentration is too low

How is the rate calculated?

Using the slope of the tangent to the line at time t

Using the average concentration over time

Using the initial concentration

If we measured the disappearance of C4H9Cl and compared it to the appearance of C4H9OH, what would be true about their magnitudes?

The magnitudes would be the same

The magnitudes would be different

The magnitudes would be infinite

What is the formula for the rate of reaction given in the document?

Rate = -(Δ[C4H9Cl]/Δt) = (Δ[C4H9OH]/Δt)

Rate = (Δ[C4H9Cl]/Δt) = -(Δ[C4H9OH]/Δt)

Rate = (Δ[C4H9Cl]/Δt) = (Δ[C4H9OH]/Δt)

Rate = -(Δ[C4H9Cl]/Δt) = -(Δ[C4H9OH]/Δt)
