Kc, Kp And Equilbrium

Question 1

What is the equation for KC

Answer 1

KC = (products)/(reactants)

Question 2

In KC what should be done if there are solids / liquids in the equation

Answer 2

Ignore them

Question 3

How to calculate equilibrium

Answer 3

Start
Change
Equilibrium

Question 4

How to find mole fraction

Answer 4

Number of moles your interested in/ total number of moles

Question 5

How to calculate partial pressure

Answer 5

Mole fraction times total pressure

Question 6

What is the equation for Kp

Answer 6

Kp= partial pressure(products)/ partial pressure (reactants)

Question 7

What happens if pressure increases

Answer 7

Favours the side with fewer moles

Question 8

What happens if concentration increases

Answer 8

Shifts to reduce it

Question 9

What happens if temperature increases

Answer 9

Favours the endothermic side

Question 10

What does a KC of more than one say

Answer 10

Equilibrium to the right

Question 11

What does a KC of Less than one tell you

Answer 11

Equilibrium to the left

Question 12

What does KC 1 mean

Answer 12

Equilibrium in the middle

Question 13

In an exothermic reaction what happens to KC as temperature rises

Answer 13

KC goes down

Question 14

In an endothermic reaction what happens to KC as temperature rises

Answer 14

It increases

Question 15

What happens if Kp decreases exothermic

Answer 15

Products and reactants must go down

Question 16

What happens if Kp increases in an endothermic

Answer 16

Partial pressure of products must go up. Partial pressure of reactants must go down

Question 17

What happens in KC if reactant increases

Answer 17

Product must increase which leads to reactant decreasing

Question 18

How to shift equilibrium to right Kp

Answer 18

Pressure of products increase, pressure of reactants decrease

Question 19

Does a catalyst effect equilibrium

Answer 19

No just rate
