DQuestion 1 2 pts Select the statements below that are TRUE. Kc and Kp are the same thing as the k (rate constant) that you learned about before. Kc has units of molarity and Kp has units of pressure D Kp uses the same equation as Kc, but with pressure instead of concentration Kc is equal to Kp when the number of moles of gas (n) doesn't change. Solids and liquid are not included in the Kc and Kp equations...
