Transcribed Image Text:Q2
Sulphur trioxide gas is obtained by the combustion of pyrites (FeS2) according
to the following reaction:
4FES2 + 1502 2Fe,03 + 8S03
The reaction is accompanied by the following side reaction:
4FES2 + 110, – 5FE203 + 8S02
Assume that 80% (weight) of the pyrites charged reacts to give sulphur trioxide
and 20% reacts giving sulphur dioxide.
a) How many kilograms pf pyrites charged will give 100 kg of SO,?
b) How many kilograms of oxygen will be consumed in the reaction?
Mwt:
C,H, = 42, NH3 = 17,02 = 32, C,H,N = 53, H,0 = 18, N2 = 28, FeS, = 120
Fe,03 = 136, SO, = 80, SO2 = 64
