Equilibrium Constant, Kp Flashcards
1
Q
What is the equation for Kp?
A
Kp = products/reactants
(Pa + Pb / Pc + Pd)
2
Q
What are the units for Kp?
A
kPa
3
Q
State what is meant by the term ‘partial pressure’
A
The pressure a gas would exert if it occupied the container alone
4
Q
How do you work out the mole fraction (Xa)?
A
Xa = no. moles of gas A/total no. of moles of gas
5
Q
How do you work out the partial pressure of a gas (Px)?
A
Px = mole fraction of X x total pressure
6
Q
State what is meant by the rate determining step
A
The slowest step, which defines how fast a reaction is
