Kp

Question 1

Define partial pressure

Answer 1

The pressure a gas in a mixture of gases would exert alone if it occupied a vessel of the same volume at the same temperature

Question 2

What does Dalton’s Law of partial pressures state?

Answer 2

The total pressure of a mixture of ideal gases is the sum total of all the partial pressures of the gases

Question 3

How do you find the concentration of an ideal gas

Answer 3

Use pV=nRT and rearrange to get (n/v)=p/(RT)

Question 4

Define mole fraction

Answer 4

The fraction of the total number of moles which is that gas

Question 5

What should the total of all the mole fractions equal?

Answer 5

1

Question 6

Give the equation to find the partial pressure

Answer 6

mole fraction x total pressure

Question 7

Is Kp affected by changes in the total pressure?

Answer 7

No

Question 8

Question 9

Is Kp affected by the presence of a catalyst?

Answer 9

No

Question 10

Is Kp affected by temperature?

Answer 10

Yes
