Question

Ce volum de etena, masurat la 127 grade celsius si 3 atmosfere, se formeaza prin dehidroclorurarea a 645 Kg monocloroetan, daca randamentul reactiei este de 80%?

Answer 1

 CH3-CH2-Cl        ---->   CH2=CH2 + HCl

64,5 g cloretan..............1 mol

645000 g cloretan..........x moli       

x = 10000 moli (10 kmoli)

η = ν practic/ ν teoretic *100 = =>      ( ν= nr.moli - niu)

ν practic= η* ν teoretic /100= 80*10/100= 8 kmoli

pV= ν *R*T => V = 8*0,082*400/3=87,466 mc
