Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Example : Reaction of iron nails with copper sulphate solution.
1) mol fraction of gas X= 2/(6+2)=2/8=1/4
2) mol fraction of gas Y= 6/(6+2)=6/8=3/4
3) Partial pressure of X = 1/4*2.1 atm=0.53 atm
4) Partial pressure of Y = 3/4*2.1=1.6 atm
Bruhhhhhhhhhhhhhhhhhhhhhh
Its either b or c, but i think its b
