Question 1

Kc is unaffected by…

Answer 1

• change in concentration
• presence of catalyst
• change in pressure

Question 2

Partial pressure definition

Answer 2

1. pressure that would be exerted by a gas
2. in a mixture of gases
3. if it occupied the same volume on its own
4. at the same temperature

Question 3

Mole fraction formula

Answer 3

mole of component/ total amount of moles in mixture

Question 4

Partial pressure formula and units

Answer 4

mole fraction x total pressure of mixture
KPa

Question 5

Equilibrium total pressure

Answer 5

1. sum of partial pressures of components in equilibrium
2. is equal to total pressure

Question 6

Mole fraction definition

Answer 6

1. amount in moles of a component
2. in a mixture
3. divided by the total moles
4. of all the components
