Flashcards in Unit 3 - The Harbor Process Deck (17):
1

What will the equilibrium do if the temperature is decreased?

It will move to try to inscrease the temperature 

2

In a reversible reaction, if the forwards reaction is exothermic, what is the backwards reacton?

Endothermic

3

In general, what temperatures are exothermic reactions favoured by?

Low temperatures

4

In general, what temperatures favour endothermic reactions?

high temperatures

5

What with the equilibrium do if the pressure is increased?

The equilibrium will move to try to decrease the pressure

6

In general what sort o reactions does high pressure favour?

Reactions with more molecules of reactant that product

7

In general, what reactions does low pressure favour?

Reactions with more molecules of product than reactants

8

What is the effect of a catayst on equilibrium?

It doesnt efect the position of equilibrium, but it means its reached quicker

9

In an endothermic reaction, what does increasing the temperature do?

increases the yield

10

In an exothermic reaction, what does decreasing the temperature do?

increases the yield

11

What is the harbor process used to make?

Ammonia, which is used to make fertilisers

12

What raw matericlas are used in the Harber process?

Hydrogen and Nitrogen

13

What ratio are nitrogen and hydrogen reacted at?

 N 1:3 H

14

What pressure and temperature is the harbor process done at?

Pressure: 200 atmospheres

Temperature: 450°C

15

What are the main uses of ammonia?

In the household, it removes grease because it is a weak alkali

Industrially in making: Nitric acid and Fertilisers (eg ammonium nitrate)

16

What catalyst is used in the Haber process?

An iron catalyst
