Q

what is a reversible reaction

A

a reaction that is able to go both ways
this means that the products of the reaction are able to react together to produce the reactants

Q

name all the parts of an ammonia processor in order

A

add
nitrogen
then hydrogen
mix it in the mixer
compressor
chamber
underacted gas recycled
then ammonia is made
then its chilled

Q

what happens when you have a low temperature and very high pressure

A

low temperature mean the rate of reaction will be too slow so there will be a low yield
high pressure is really expensive

Q

how do you test for ammonia give its ionic equation

A

react it with sodium hydroxide the pass the gas through red litmus paper if it turns blue then
it means ammonia is present

NH4+(aq) + OH+ +NH3 (g) +h2o(l)

Q

tell me all the steps of making sulphuric acid

A

sulphur is roasted in oxygen

S +O2 ——->so2

then the sulphur dioxide reacts with more o2
so2 +o2 ———>2so3
then they react the sulphur tri oxide with sulphuric acid to make ole um
2so3 +h2so4 —–> 4 h2so4 this is a dehydrating agent

19
Q

why are the unreacted gases recycled

A

in order to not wast e underacted materialshow

20
Q
