KP

Question 1

How does an increase in temperature affect Kp for an exothermic reaction

Answer 1

Exothermic reactions: Temperature rise: - position of equilibrium moves to left, Kp and Kc become smaller

Question 2

How does an increase in temperature affect Kp for an endothermic reaction

Answer 2

Endothermic reactions: Temperature rise: - position of equilibrium moves to right, Kp and Kc become bigger

Question 3

How does Kp change as we decrease temperature for an exothermic reaction

Answer 3

Temperature fall: Position of equilibrium moves to the right, Kp and Kc become bigger

Question 4

How does Kp change as we decrease temperature for an endothermic reaction

Answer 4

Temperature fall: Position of equilibrium moves to the left, Kp and Kc become smaller

Question 5

Which factors don’t affect Kp or Kc

Answer 5

Concentration, pressure, or the addition of a catalyst

Question 6

If we divide an original equation by factor n, with a known kp, what becomes the Kp of the new equation

Answer 6

If you multiply all the stoichiometric coefficients in a balanced equation by a factor 𝑛, then the new equilibrium constant becomes
𝐾pnew=(Kporiginal)ⁿ

Question 7

If we flip an equation around, what becomes the new value of Kp

Answer 7

1/Kporiginal
