AP Chemistry 7.6 Equilibrium Constant Manipulation Question Bank

Practise AP Chemistry 7.6 equilibrium questions by combining reactions, reversing equations and tracking how K expressions change.

Exam points

combine reactions and multiply, divide or invert equilibrium constants consistently
explain that compression changes composition but only temperature changes K at equilibrium

Answer the following questions about $\mathrm{C}_{2} \mathrm{H}_{4} \mathrm{O}$ .

(g) The sample is compressed to half of the original volume, without any change in temperature. Does the value of $K_{p}$

increase, decrease, or remain the same? Justify your choice.

Part G

Select a point value to view scoring criteria, solutions, and/or examples and to score the response.

The response provides a correct answer and a valid justification.

- $K_{p}$ will remain the same. Only a temperature change can alter the value of K.

2022 Form I

- $K_{p}$ will remain the same. Changing the volume of the container does not change the $K_{p}$ value.
