N2 + 3H2 equilibrium 2NH3
what is the chemical equation for the haber process?
rate of reaction
complete the sentence, " at low temperatures the yield is high but the **** ** ******** is slow
the smallest amount of energy particles need to react
what is the activation energy?
covalent compound
What kind of compound can not be split by electrolysis?
decreases the yield
increasing pressure does what to a reaction?
thermal decomposition and photosynthesis
give two examples of endothermic reactions
soap or paper
Industrial use of Sodium hydroxide
a substance that speeds up a chemical reaction but is not itself chemically affected by the
reaction
definition of a catalyst
it decreases
if a I increase the temperature of an exothermic reaction, what happens to the yield?
an iron catalyst?
what catalyst can we use to speed up the haber process?
the more pressure, the closer the particles therefore there are more collisions
why does increasing the pressure in a reaction increase the rate? refer to particles in your
answer
chlorine and sodium hydroxide
what forms when we electrolyise brine?
respiration, neutrilisation
give two examples of exothermic reactions
the anode
the cations are atrracted to what?
accept bleach production, purifying swimming pools, PVC production and anal lubrication
Give a use of chlorine
cathode
the negative electrode?
particles collide more often and with more energy
what two things happen in relation particles in a reaction when the temperature is increased?
reduction
What is the process called in which ions gain electrons to become atoms?
sodium chloride solution
what is brine?
Mr.Clarke
Charles de gaulle looks like which GSAL english teacher?
200 atmospheres at 450 degrees centigrade
what is the compromise pressure and temperature for the haber process?
the electrolyte
What is the name given to the substance broken down by electrolysis
anode
What is the name of the positive electrode?
increases it
increasing temperature in an endothermic reaction does what to the yield?
The decomposing (break down) of a substance by passing an electric current through it
define: electrolysis
the less reactive one
In electrolysis in water, two elements could potentially form at an electrode. Which of the
two elements would form at the electrode?
temperature, surface area, concentration and catalyst
what are the four main factors that affect the rate of reaction?
oxidation
What is the process called in which ions lose electrons to become?
impurities
before getting pure copper we must get rid of its what?
