kp

Question 1

when do u use kp

Answer 1

for a gas

Question 2

definition of a homogenous system

Answer 2

a homogeneous system is where all reactants and products are in the same phase

Question 3

all mole frac added together =

Answer 3

1

Question 4

partial pressure equation

Answer 4

partial pressure = mole frac of X x total pressure

Question 5

mole fraction equation

Answer 5

number of moles x in the mixture / total number of moles of all gases

Question 6

how to write a kp equation

Answer 6

products / reactants
rounded brackets to show partial pressure eg 4co2 =(ppco2)^4

Question 7

features of kp

Answer 7

kp>1 equilibrium towards the right - more products than reactants
kp< 1 equilibrium towards the left - more reactants than products
kp = 1 equilibrium is in the middle - equal amounts of products and reactants

Question 8

only condition that has an affect on kp value

Answer 8

change in temperature

Question 9

how would a decrease in temp affect the value of kp

Answer 9

value of kp will increase
forward reaction is exothermic
equilibrium will shift to oppose the decrease in temperature
