2 muaj daim ntawv ntawm algebraic kev sib npaug rau ib txoj kab ncaj nraim, y = mx + b, nrog y = [A], mx = −kt, thiab b = [A]0.) Ib a zeroth - xaj tshuaj tiv thaiv , tus nqi tas li yuav tsum muaj tib lub units raws li qhov tshuaj tiv thaiv tus nqi, feem ntau moles ib liter ib ob.
Kuj nug, qhov kev txiav txim xoom yog dab tsi?
Kev txhais ntawm xoom - xaj tshuaj tiv thaiv : ib chemical tshuaj tiv thaiv uas tus nqi ntawm tshuaj tiv thaiv yog tas li thiab ywj siab ntawm cov concentration ntawm cov tshuaj reacting - piv xaj ntawm a tshuaj tiv thaiv.
Kuj Paub, yog photosynthesis yog xoom xaj tshuaj tiv thaiv? Teb: Tag nrho cov photochemical cov tshuaj tiv thaiv yog xoom xaj tshuaj tiv thaiv . Teb: Tag nrho cov photochemical cov tshuaj tiv thaiv yog xoom xaj tshuaj tiv thaiv.
Hais txog qhov no, txoj kab nqes ntawm qhov kev txiav txim xoom yog dab tsi?
Rate Laws from Graphs of Concentration Versus Time (Integrated Rate Laws)
| Rau qhov kev txiav txim xoom, | pes = k | (k = - txoj kab nqes) |
|---|---|---|
| Rau ib qho 1st xaj tshuaj tiv thaiv, | tus nqi = k[A] | (k = - txoj kab nqes) |
| Rau ib 2nd xaj tshuaj tiv thaiv, | tus nqi = k[A]2 | (k = txoj kab nqes) |
Dab tsi yog xoom thawj thiab thib ob kev txiav txim tshuaj tiv thaiv?
A xoom - xaj tshuaj tiv thaiv ua tiav ntawm tus nqi tas li. A ua ntej - xaj tshuaj tiv thaiv tus nqi nyob ntawm qhov concentration ntawm ib qho ntawm cov reactants. A thib ob - xaj tshuaj tiv thaiv tus nqi yog proportional rau lub square ntawm cov concentration ntawm ib tug reactant los yog cov khoom ntawm concentration ntawm ob reactants.
