partial pressure and Kp

Question 1

calculate partial pressure

Answer 1

mole fraction * total pressure

Question 2

calculate mole fraction

Answer 2

number of moles of a gas / total number of moles of all gases

Question 3

what is the unit of Kp?

Answer 3

kPa

Question 4

what does a small or large Kp mean?

Answer 4

large = greater amount of product 
smaller = equilibrium favours the reactants

Question 5

what factors effect and dont effect Kp and Kc?

Answer 5

temp changes both

pressure, concentration and catalysts = no impact

Question 6

what is the impact of temperature on Kc and Kp and equilibrium?

Answer 6

both of them will change

• if the reaction is exothermic in the forward direction, if temp increases the reaction will shift to oppose the chnage and move in the backwards endothermic direction.
• the position of equilibrium shifts left.
• the value of kp gets smaller as there are fewer products

Question 7

what is the impact of pressure on position of equilibriym and Kp

Answer 7

• the position of equilibrium will change if pressure is altered but he value of Kp stays constant as Kp only varies with temp.
• equilibrium shifts to the side with fewer moles
