Equilibrium Constants and ICE Tables

The video tutorial explains the reaction of iron(II) oxide with carbon monoxide, leading to solid iron and carbon dioxide. It discusses the equilibrium constant Kp and how to calculate the equilibrium partial pressures of carbon monoxide and carbon dioxide using the reaction quotient Qp. The tutorial uses an ICE table to determine changes in partial pressures and solve for equilibrium conditions, verifying the results by comparing Qp and Kp.

What is the equilibrium constant Kp for the reaction at 1000 Kelvin?

• 0.40

• 0.80

• 0.50

• 0.26

If Qp is greater than Kp, in which direction will the reaction proceed?

• No change

• To the right

• Cannot be determined

• To the left

What does the 'I' in the ICE table stand for?

• Intermediate

• Inert

• Initial

• Increment

In the ICE table, what is the initial partial pressure of carbon monoxide?

• 0.40 atm

• 0.80 atm

• 0.95 atm

• 0.25 atm

What is the expression for Kp in terms of partial pressures for this reaction?

• Partial pressure of CO2 only

• Partial pressure of CO divided by CO2

• Partial pressure of solids

• Partial pressure of CO2 divided by CO

What is the value of x when solving for equilibrium partial pressures?

• 0.20

• 0.15

• 0.25

• 0.10

What is the equilibrium partial pressure of carbon monoxide?

• 0.25 atm

• 0.80 atm

• 0.95 atm

• 0.40 atm

What is the equilibrium partial pressure of carbon dioxide?

• 0.25 atm

• 0.40 atm

• 0.80 atm

• 0.95 atm

How do you verify that the calculated equilibrium partial pressures are correct?

• By recalculating Qp and checking if it equals Kp

• By comparing initial pressures

• By measuring the volume

• By checking the temperature

What does it mean if Qp equals Kp at equilibrium?

• The reaction has stopped

• The reaction is still proceeding

• The reaction is at equilibrium

• The reaction is irreversible
