Topic 4- Reversible reactions and equilibria

Question 1

What reactions have ⇌ ?

Answer 1

-Reversable reactions
-Change conditions to reverse reaction

Question 2

What is dynamic equilibrium?

Answer 2

-Forward and backward reaction at same rate

Question 3

How is ammonia produced in dynamic equilibrium?

Answer 3

-Hydrogen + Nitrogen ⇌ ammonia

3H2 + N2 –> 2NH3

Question 4

What is the condtion for the Haber process?

Answer 4

Temperature: 450°C degrees
Pessure: 200 atm
Iron catalyst

Question 5

How does a change in temp effect haber process?

Answer 5

Higher= more reactants
Lower= More ammonia

Question 6

How does a change in pressure effect haber process?

Answer 6

Higher= more ammonia
Lower= More reactants

Question 7

How does a change in conc effect haber process?

Answer 7

-More succesfull collisions
-more reactants= more products and vice versa
