Equilibrium Systems and Graphs Quiz

What is the primary focus of using graphs in equilibrium systems?

• To determine the speed of a reaction

• To describe and illustrate changes in equilibrium

• To predict the future state of a system

• To calculate the exact amounts of reactants and products

In a graph of an equilibrium system, what does a horizontal line represent?

• A reaction that is slowing down

• The equilibrium position

• The initial state of the system

• A reaction that is speeding up

What principle helps predict the shift in equilibrium when a change occurs?

• Avogadro's Law

• Dalton's Law

• Le Chatelier's Principle

• Boyle's Law

What happens to the equilibrium when the concentration of a reactant is increased?

• The system shifts to decrease the product concentration

• The system remains unchanged

• The system shifts to increase the reactant concentration

• The system shifts to decrease the reactant concentration

How does a decrease in reactant concentration affect the equilibrium?

• The system shifts to increase the product concentration

• The system shifts to decrease the product concentration

• The system shifts to increase the reactant concentration

• The system remains unchanged

When pressure is increased in a gaseous equilibrium system, what is the typical response?

• The system shifts to the side with more particles

• The system shifts to the side with fewer particles

• The system remains unchanged

• The system shifts to increase the volume

What is the effect of decreasing pressure on a gaseous equilibrium system?

• The system shifts to the side with more particles

• The system shifts to decrease the volume

• The system remains unchanged

• The system shifts to the side with fewer particles

How does an increase in temperature affect an exothermic equilibrium reaction?

• The system shifts to the right

• The system remains unchanged

• The system shifts to increase the temperature

What happens to an endothermic reaction when the temperature is decreased?

• The system shifts to the right

• The system shifts to the left

• The system shifts to decrease the temperature

In the context of equilibrium, what does an endothermic reaction do?

• Absorbs heat

• Releases heat
