Equilibrium yog txiav txim los ntawm kev ntxiv "Initial" thiab " Hloov ua ke. Yog tias x = 1.78 ces [C2H4]Eq yog qhov tsis zoo, uas tsis yooj yim sua, yog li, x yuav tsum sib npaug 0.098.

Ua raws li qhov xav tau, tus nqi sib npaug li cas?

Upward hloov hauv cov khoom siv thiab kev xav tau nkhaus cuam tshuam rau tus nqi sib npaug thiab kom muaj nuj nqis. Yog hais tias cov khoom siv nkhaus hloov mus rau sab saud, lub ntsiab lus ntawm cov khoom txo qis tab sis kev thov tuav ruaj khov, qhov tus nqi sib npaug nce tab sis kom muaj nuj nqis poob. Piv txwv li, yog tias cov khoom siv roj av poob, twj tso kua mis tus nqi zoo li yuav sawv.

Ib tug kuj yuav nug, ua li cas koj thiaj li nrhiav tau qhov sib npaug ntawm qhov nqus dej? Yog li ntawd, [Fe(SCN)2+]ua eq tuaj yeem txiav txim ncaj qha los ntawm absorbance kev ntsuas. Equilibrium concentrations ntawm cov reactants tuaj yeem xam los ntawm kev rho tawm equilibrium concentration ntawm qhov khoom los ntawm qhov pib concentrations ntawm cov reactants.

Ntawm no, ua li cas koj xam equilibrium?

Txhawm rau txiav txim siab tus nqi sib npaug, ua cov hauv qab no

  1. Teem kom muaj nuj nqis sib npaug rau qhov khoom muab:
  2. Ntxiv 50P rau ob sab ntawm qhov sib npaug. Koj tau txais.
  3. Ntxiv 100 rau ob sab ntawm qhov sib npaug. Koj tau txais.
  4. Faib ob sab ntawm qhov sib npaug los ntawm 200. Koj tau txais P sib npaug $ 2.00 rau ib lub thawv. Qhov no yog tus nqi sib npaug.

Yuav ua li cas koj xam tus nqi sib npaug tshiab thiab kom muaj nuj nqis tom qab them se?

Nrog $4 se ntawm cov neeg tsim khoom, cov khoom siv nkhaus qab se yog P = Q/3 + 4. Li no, the tshiab equilibrium kom muaj nuj nqis tom qab se tuaj yeem pom los ntawm kev sib npaug P = Q / 3 + 4 thiab P = 20 - Q, yog li Q / 3 + 4 = 20 - Q, uas muab QT = 12. Nqe producers tau txais yog los ntawm pre- se muab kev sib npaug Pnet = QT/3 = 12/3 = 4.
