Reversible Reactions

Question 1

What is a reversible reaction?

Answer 1

Where the products can react with each other to produce the original reactants.

Question 2

Describe what happens in the haber process

Answer 2

Nitrogen + hydrogen->ammonia. Nitrogen is obtained easily from air. Hydrogen extracted from hydrocarbons from sources like natural gas + crude oil.

Question 3

How is the haber process carried out?

Answer 3

At 450°c which pressure of 200 atmospheres + an iron catalyst

Question 4

What is a dynamic equilibrium?

Answer 4

Forward + backward reactions both happening at same time + same rate. Concentrations of reactants + products have reached a balance so won’t change.

Question 5

What conditions are needed for a dynamic equilibrium to be achieved?

Answer 5

Reversible reaction, closed system so products/reactants can’t escape.

Question 6

What 3 things affect an equilibrium?

Answer 6

Temperature
Pressure
Concentrations
