1
Q
What is Kp deduced from
A
From the equation for a reversible reaction in the gas phase
2
Q
What is Kp
A
The equilibrium constant calculated from partial pressures for a system at constant temperature
3
Q

A
Number of moles of gas a in a mixture/
Total number of moles in a mixture
4
Q
How do you work out partial pressure
A
Number of moles of gas a X total pressure
5
Q
What effects Kp
A
Temperature
Pressure effects equilibrium yield but not Kp
6
Q
What does a Kp equation look like
A
Kp = (pHI)^2
p(H2) (pI2)
7
Q
Kp units
A
Works the same was as Kc units but with kPa
