Question 1

what is the mole fraction?

Answer 1

proportion by volume to the total volume of gases in a mixture

Question 2

what is the equation for the mole fraction?

Answer 2

number of moles of gas/total number of moles of gas in mixture

Question 3

what is partial pressure?

Answer 3

in a mixture of gases, each individual gas exerts its own pressure

Question 4

how is partial pressure written?

Answer 4

p(X)

Question 5

how is total pressure written?

Answer 5

p(A) + p(B) + p(C) = ptotal

Question 6

when is Kp used?

Answer 6

when the equation has gases only

Question 7

what is the equation for the partial pressure of gas in a mixture?

Answer 7

partial pressure of gas in a mixture = mole fraction of gas x total pressure of the mixture

Question 8

how is Kp written?

Answer 8

Kp = p(products)/ p(reactants)

Question 9

what changes the value of Kc/Kp?

Answer 9

temperature

Question 10

what does not change the value of Kp/Kc?

Answer 10

concentration, pressure and catalyst

Question 11

how does temperature change the value of Kc/Kp?

Answer 11

• if temperature increases:
  1) forward reaction is endothermic(+ve) = Kc/Kp value increases
  2) forward reaction is exothermic(-ve) = Kc/Kp value decreases
