Kc & Kp Units

The video tutorial explains the units of equilibrium constants KC and KP, focusing on their application in gaseous equilibrium reactions. It discusses the formation of nitric oxide from nitrogen and oxygen, highlighting that the number of moles of reactants and products are equal, resulting in KP equaling KC with no units. The dissociation of phosphorus pentachloride into phosphorus trichloride and chlorine is also examined, showing how delta N affects the units of KC and KP, with KP expressed in atmospheres.

What does the unit of KC represent in terms of molarity?

• Moles per liter squared

• Atmospheres raised to the power of delta N

• Atmospheres squared

• Moles per liter raised to the power of delta N

In the formation of nitric oxide, what is the value of delta N?

• 1

• 0

• -1

• 2

For the reaction forming nitric oxide, what is the relationship between KP and KC?

• KP is greater than KC

• KP is less than KC

• KP is unrelated to KC

• KP equals KC

In the dissociation of phosphorus pentachloride, what is the calculated value of delta N?

• 2

• -1

• 1

• 0

What are the units of KP for the dissociation of phosphorus pentachloride?
