Question

Calculati cantitatea de tetraclorura de carbon obtinuta din 448 litri metan de puritate 90%, considerand randamentul reactiei de 80 % , repede vă rog

Answer 1

puritatea = p% = Vpx100/Vip

=> Vp = Vioxp%/100 = 448x90/100 = 403,2 L

403,2 L ............................................................ V L

CH4 + 4Cl2 -$-\frac{hv}{-4HCl}-$-> CCl4

22,4..................................................................... 22,4

=> V = 403,2x22,4/22,4 = 403,2 L la rand. de 100% dar noi avem 80%

=> randament = n = Vpracticx100/Vteoretic

=> Vpractic = Vteoret x 80/100 = 403,2x80/100 = 322,56 L CCl4
