How do acids taste
Sour
100
What does a reaction between an acid and a base produce
Water and a salt
100
What does the pH scale show us
Concentration of hydrogen ions
100
What catalyst is used to speed up the Haber process
Iron
100
What is the contact process
The process of making sulfuric acid
200
Who the the Haber process named after
Fritz Haber
200
What are the two causes of acid rain
Sulfur and nitrogen oxides
200
Why don't we dissolve sulfur trioxide in water
Makes a fog of sulfuric acid (dangerous)
200
If lower temperatures increase the forward yield of Haber process why don't we set the temperature as low as we can
It decreases the rate of reaction
300
Why is increasing pressure too much, a very unpractical way on increasing the forward yield of hater process
Its too expensive
300
How does decreasing pressure affect the equilibrium
Shifts it to a side with more gas molecules
300
What does the presence of a catalyst do to a reversible reaction and Kc
Kc does not change Rate of both forward and backward reactions increase
300
What is the Lewis theory
Acids are electron pair acceptors Bases are electron pair donors
300
Give an example of what the Arrhenius their doesn't explain
Ammonia being a base
400
What is the pH formula?
pH=-log[H]
400
What makes a strong acid
Strong acids completely dissociate.
400
Where will the equilibrium move if the concentration of one of the reactants increases
To the right
400
How to increase the forward yield of the Haber reaction Explain your answer
Decrease temp (the equilibrium will shift to the right as the forward reaction is exothermic)
400
Apart from increasing temperature what is another practical way of increasing the amount of ammonia produced in the Haber process
Increase pressure (shorts equilibrium to a side with fewer gaseous molecules)
500
What is the Arhenious theory
Acids contain hydrogen ions Bases contain hydroxide ions
500
What is the Bronsted-Lowry theory
Acids are proton donors Bases are proton acceptors
500
What affects Kc value
Temperature
500
What is the Le Chatelier principle
If a product is removed the Kc remains the same but the equilibrium shifts toward the products side
500
How does increasing oxygen concentration in the contact process, increase the sulfur dioxide yield and why is it a cheap way of making more sulfur dioxide.
Shifts equilibrium to the right Plenty of oxygen in the air
