What is the purpose of using an ICE table in equilibrium problems?

• To determine the reaction rate

• To find the temperature of the reaction

• To organize and calculate changes in concentrations

• To calculate the initial concentrations

How do you determine the direction of the reaction shift using the reaction quotient (QC)?

• By comparing QC to the temperature

• By comparing QC to the KC value

• By comparing QC to the pressure

• By comparing QC to the volume

What does a QC value less than KC indicate about the direction of the reaction?

• The reaction will stop

• The reaction will shift to the left

• The reaction is at equilibrium

• The reaction will shift to the right

What is the next step after determining the equilibrium concentrations using the ICE table?

• Measure the temperature

• Plug the values into the KC expression

• Calculate the reaction rate

• Determine the pressure

Which mathematical method is used to solve for X in equilibrium problems?

• Exponential function

• Quadratic formula

• Linear equation

• Logarithmic function

Why is it important to verify the solution of X in equilibrium problems?

• To confirm the reaction rate

• To ensure the solution is positive and makes sense

• To check the temperature

• To validate the pressure

What should you do if you get a negative concentration when solving for X?

• Recalculate the initial concentrations

• Ignore the negative value and choose the positive one

• Change the KC value

• Use the negative value

What is the significance of the KC expression in equilibrium problems?

• It finds the reaction rate

• It measures the pressure

• It determines the temperature

• It is used to calculate equilibrium concentrations

How can you verify the calculated equilibrium concentrations?

• By checking the temperature

• By measuring the pressure

• By comparing them to the initial concentrations

• By plugging them back into the KC expression

What is the final step in solving an equilibrium problem?

• Calculating the reaction rate

• Verifying the equilibrium concentrations
