Equilibrium Flashcards
1
Q
What does a Kc value tell you ?
A
Tells you how far the reaction has gone- which side it leans to but it does not tell you anything about the rate (speed) of the reaction.
2
Q
What is the Contact Process ?
A
The industrial manufacture of sulfuric acid.
3
Q
Give one commercial use of the contact process ?
A
- fertilisers
- paints
- plastics
- car batteries
4
Q
Name the catalyst used for the Contact Process
A
Vanadium Pentoxide ( V²O⁵)
5
Q
What is the condition for the Contact Process to take place ?
A
That there had to be very close contact between the two gases for the reaction to take place
6
Q
- Equation of the Contact Step
A
2SO² + O² < 2SO³
>
7
Q
How is sulfuric acid made ?
A
Sulfuric acid is made by dissolving the Sulfur trioxide made in the reaction of the contact step reaction in water.
8
Q
Optimum conditions of the Contact Process
A
- to keep costs down snd prevent SO² from liquefying a pressure JUST ABOVE AUTMOSPHERE PRESSSURE IS USED
- For the catalyst to work at optimum rate and so the reaction is not slow a temperature of 450°C is used
