Kp Flashcards
1
Q
What is Kc only affected by?
A
Temperature
2
Q
When using ICE, is it addition & subtraction, or multiplication & division?
A
Addition & subtraction
3
Q
Why is is more convenient to use pressure measurements to calculate equilibrium constants, generating expressions for Kp?
A
Many industrial processes involve gaseous systems
4
Q
What are partial pressures(p)?
A
In an equilibrium mixture of gases, each component will contribute to the pressure
5
Q
What is the total pressure(P)?
A
Sum of pressures of all gases
6
Q
What is equation for mole fraction?
A
Moles/total moles
7
Q
What is equation for P?
A
P = pA + pB + pC
8
Q
What is Kp expression for N2(g) + 3H2(g) <—> 2NH3(g)? Units?
A
Kp = (pNH3)2 / (pN2)(pH2)3
Kp = kPa2 / kPa x kPa3 = kPa-2
