Cov lub hom phiaj ntawm no kev sim yog to txiav txim tus equilibrium tsis tu ncua rau cov tshuaj tiv thaiv. Fe3+ + SCN. - ⇌ FeSCN2+ thiab saib seb cov tas li yeej yog tib yam nyob rau hauv txawv. tej yam kev mob.
Dhau li ntawm qhov no, txhais tau li cas los ntawm qhov sib npaug tas li thiab nws yuav txiav txim siab li cas?
Los ntawm Wikipedia, dawb encyclopedia. Equilibrium tas li yog txiav txim txhawm rau txheeb xyuas cov tshuaj equilibria . Thaum ib equilibrium tsis tu ncua K yog qhia raws li ib tug concentration quotient, nws yog implied hais tias cov kev ua quotient yog tas li.
Ib yam li ntawd, koj yuav ua li cas thiaj nrhiav tau qhov sib npaug tas li ntawm absorbance? X = [Fe(SCN)2+] thiab yuav tsum tau txiav txim los ntawm tus qauv nkhaus. Koj ua tau ces xam tus equilibrium tsis tu ncua , Keq, use the kev sib npaug concentrations. Tus qauv nkhaus yog ib zajlus ntawm Absorbance versus [Fe(SCN)2+] (Daim duab 8.1). Nws tuaj yeem siv los muab peb cov concentration ntawm kev daws teeb meem thaum muab cov absorbance.
Xav txog qhov no, dab tsi txiav txim siab qhov equilibrium tas li?
ib tug thermodynamic equilibrium tsis tu ncua , denoted los ntawm, txhais tau tias yog tus nqi ntawm cov tshuaj tiv thaiv quotient Qt thaum muaj kev cuam tshuam rau pem hauv ntej thiab rov qab tshwm sim ntawm tib tus nqi. Ntawm chemical kev sib npaug , cov tshuaj muaj pes tsawg leeg ntawm cov sib tov tsis hloov nrog lub sij hawm thiab Gibbs dawb zog hloov rau cov tshuaj tiv thaiv yog xoom.
Koj ntsuas qhov sib npaug li cas?
Sau tus kev sib npaug qhia rau cov tshuaj tiv thaiv. Txiav txim siab cov molar concentrations los yog ib feem ntawm cov kab mob uas koom nrog. Txiav txim siab tag nrho kev sib npaug cov concentrations lossis ib feem ntawm cov kev ntxhov siab siv daim ntawv ICE. Hloov mus rau hauv lub kev sib npaug qhia thiab daws rau K.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog units ntawm tus nqi tas li rau thawj qhov kev txiav txim siab?
Hauv thawj qhov kev txiav txim siab, cov tshuaj tiv thaiv tus nqi yog ncaj qha rau cov reactant concentration thiab cov units ntawm firstorder tus nqi tas mus li yog 1 / sec. Hauv cov tshuaj tiv thaiv bimolecular nrog tworeactants, qhov kev txiav txim thib ob tus nqi tsis tu ncua muaj units ntawm 1 / M * sec
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
