Equillibria Kp

Question 1

what is the expression for Kp?

Answer 1

(ppC)^c (ppD)^d)
————————
(ppA)^a (ppB)^b

Question 2

What is the equation for mole fraction?

Answer 2

moles
———-
total moles

Question 3

what is the equation for partiall pressure?

Answer 3

Moles fraction X total pressure

Question 4

Outline the steps to work out partial pressure

Answer 4

• minus is the moles made at equilibrium from the reactants
• add together these more along with the moles of the products to find total moles
• Divide the total moles by the moles of each compound to get the mole fraction
• times the mole fraction by the total pressure to work out the ** partial pressure**

Question 5

What is the equation for working out partial pressure from a mole ratio?

Answer 5

sum of missing partial pressures
————————————————- x desired moles
total moles in mole ratio

Question 6

How does a change in temperature affect equilibrium?

Answer 6

increase temperature equilibrium shifts to endothermic side

decrease temperature equilibrium shifts to exothermic side

Question 7

what is the only factor that affects Kp?

Answer 7

temperature

Question 8

What is the effect on pressure in an equilibrium reaction?

Answer 8

Increase equilibrium moves to the side with less moles

decrease equilibrium moves of side with more moles

Question 9

In what scenario will pressure not have an effect on equilibrium?

Answer 9

If the number of moles are equal in the reaction

Question 10

what effect does a catalyst have on Kp and the yield?

Answer 10

no effect
