What is the purpose of a catalyst

a catalyst provides a different path for a reaction to occur

To lower the activation energy of a reaction

How does increasing the temperature affect collisions

It increases the number of high-energy collisions

Which of the following acts as a catalyst in catalytic converters

Metal

How can the rate constant be determined from the rate law

The rate constant is the reaction rate divided by the concentration terms.

How is the effect of concentration changes on the reaction rate seen in the rate law

The exponents determine how much concentration changes affect the reaction rate

Why does a reaction slow down with time

The reactant concentrations decrease

An Arrhenius acid donates H+ ions. (apex).

What information does the rate constant give from the rate law

It tells how much the reaction rate is affected by concentrations.
