7.6 - 7.7 AP Chemistry

What happens to the equilibrium constant K when a chemical reaction is reversed?

• K becomes zero

• K remains the same

• K becomes the reciprocal (1/K)

• K doubles

If the coefficients in a chemical equation are multiplied by a factor of 3, how is the new K value determined?

• K is multiplied by 3

• K remains unchanged

• K is divided by 3

• K is raised to the power of 3

In an ICE chart, what does 'C' stand for?

• Change

• Calculated

• Constant

• Complete

How is the equilibrium concentration of products calculated in an ICE chart?

• Product of initial concentration and change

• Change divided by initial concentration

• Initial concentration plus change

• Initial concentration minus change

What is the correct interpretation of a small K value in terms of product formation?

• No product is formed

• All reactants are converted into products

• Large amount of product is formed

• Negligible amount of product is formed
