KP

Question 1

What is the equation for mole fraction

Answer 1

Number of moles of gas/total number of moles

Question 2

What is the equation for partial pressure

Answer 2

Mole fraction of gas x total pressure in a mixture

Question 3

How do you work out total pressure

Answer 3

Sum of all pressures of individual gases

Question 4

How can temperature affect the value of KP

Answer 4

Kp only valid for 1 temp
Changing temp will change equilibrium pressures and then Kp

If temperature causes equilibrium to shift right KP will increase

If temperature causes equilibrium to shift left Kp will decrease

Question 5

Is Kp affected by pressure

Answer 5

The value of Kp is unaffected by any changes in pressure

Question 6

Is Kp affected by catalysts

Answer 6

Adding a catalyst has no effect on the value of Kp
Catalyst speeds up both the forward and backwards reaction
So catalyst speeds up the rate at which equilibrium will happen
