Qhov sib txawv tseem ceeb ntawm kev sib npaug ntawm cov tshuaj thermochemical thiab kev sib npaug tshuaj yog qhov sib npaug ntawm cov tshuaj thermochemical qhia qhov hloov pauv ntawm cov tshuaj tiv thaiv, qhov sib npaug tshuaj feem ntau tsis qhia qhov hloov pauv enthalpy.
Ib qhov sib npaug ntawm cov tshuaj thermochemical yog qhov sib npaug ntawm cov tshuaj stoichiometric cov tshuaj tiv thaiv uas suav nrog kev hloov pauv enthalpy, thaum qhov sib npaug tshuaj yog ib qho kev sib npaug uas qhia cov khoom pib, cov tshuaj reactants, thiab cov khoom kawg sib cais los ntawm xub.
Dab tsi yog qhov sib npaug ntawm Thermochemical?
Ib qhov sib npaug ntawm cov tshuaj thermochemical tuaj yeem piav qhia raws li qhov sib npaug ntawm cov tshuaj stoichiometric tshuaj tiv thaiv uas qhia txog kev hloov pauv enthalpy. Kev hloov pauv enthalpy yog txhais los ntawm ΔH. Hauv nws daim ntawv hloov pauv, hom tshuaj tiv thaiv zoo li A + B → C; ΔH=(±)qhov twg A thiab B yog reactants, C yog cov khoom kawg, thiab (±)yog tus lej zoo lossis tsis zoo rau kev hloov pauv enthalpy.
Enthalpy ntawm lub kaw lus yog qhov ntsuas kub sib npaug sib npaug rau tag nrho cov ntsiab lus kub ntawm lub kaw lus. Nws yog sib npaug rau lub zog sab hauv ntawm lub cev ntxiv rau cov khoom ntawm lub siab thiab ntim. Yog li ntawd, nws yog cov cuab yeej thermodynamic ntawm lub cev.
Peb tuaj yeem hloov pauv qhov sib npaug thermochemical los ntawm kev muab nws los ntawm cov lej lej. Nyob rau hauv txoj kev no, peb yuav tsum tau muab txhua tus neeg sawv cev, suav nrog kev hloov enthalpy. Piv txwv li, cov piv txwv saum toj no tuaj yeem muab faib ua "2," thiab nws muab 2A + 2B → 2C, 2ΔH=2[(±)].
Yuav ua li cas yog Chemical Equation?
Kev sib npaug tshuaj lom neeg yog ib qho kev sib npaug uas qhia txog qhov pib sib xyaw, cov tshuaj reactants, thiab cov khoom kawg sib cais los ntawm tus xub. Hauv lwm lo lus, kev sib npaug tshuaj lom neeg yog qhov sawv cev ntawm cov tshuaj tiv thaiv tshuaj. Qhov no txhais tau hais tias cov tshuaj sib npaug muab cov reactants ntawm cov tshuaj tiv thaiv, cov khoom kawg, thiab cov kev taw qhia ntawm cov tshuaj tiv thaiv ib yam nkaus. Muaj ob hom kev sib npaug: sib npaug sib npaug thiab skeleton equations.
Kev sib npaug tshuaj sib npaug muab cov naj npawb ntawm cov reactants uas sib cuam tshuam nrog ib leeg thiab cov khoom lag luam molecules tsim. Nws yog ib qho kev sib npaug tag nrho uas qhia txog qhov sib piv ntawm cov reactants thiab cov khoom. Thaum xam cov parameter xws li tus nqi ntawm cov khoom peb tau txais los ntawm cov tshuaj tiv thaiv, peb yuav tsum siv cov tshuaj sib npaug sib npaug; txwv tsis pub, peb yuav tsis paub ntau npaum li cas reactants reacted muab ntau npaum li cas ntawm cov khoom.
Ib qho kev sib npaug ntawm lub cev qhia txog hom reactants koom nrog cov tshuaj tiv thaiv thiab cov khoom kawg. Txawm li cas los xij, qhov no tsis muab qhov tseeb piv ntawm cov reactants thiab cov khoom. Yog li, cov ntsiab lus tseem ceeb uas peb tuaj yeem tau txais los ntawm kev sib npaug ntawm cov pob txha yog cov reactants ntawm cov tshuaj tiv thaiv, cov khoom ntawm cov tshuaj tiv thaiv, thiab cov kev taw qhia ntawm cov tshuaj tiv thaiv.
Qhov txawv ntawm Thermochemical Equation thiab Chemical Equation yog dab tsi?
Hauv chemistry, ib qho kev sib npaug qhia cov molecules koom nrog hauv cov tshuaj tiv thaiv tshwj xeeb thiab cov kev taw qhia ntawm cov tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm qhov sib npaug ntawm cov tshuaj thermochemical thiab cov kab zauv tshuaj yog qhov sib npaug ntawm cov tshuaj thermochemical ib txwm qhia qhov hloov pauv ntawm cov tshuaj tiv thaiv, qhov sib npaug ntawm cov tshuaj tsis feem ntau qhia qhov hloov pauv enthalpy.
Cov hauv qab no qhia txog qhov sib txawv ntawm qhov sib npaug ntawm cov thermochemical thiab kev sib npaug tshuaj. nyob rau hauv daim ntawv tabular rau ib sab sib piv
Summary – Thermochemical Equation vs Chemical Equation
Ib qhov sib npaug ntawm cov tshuaj thermochemical yog qhov sib npaug ntawm cov tshuaj stoichiometric cov tshuaj tiv thaiv uas suav nrog kev hloov pauv enthalpy, qhov sib npaug ntawm cov tshuaj lom neeg yog ib qho kev sib npaug uas qhia cov khoom pib, cov tshuaj reactants, thiab cov khoom kawg sib cais los ntawm tus xub. Qhov sib txawv tseem ceeb ntawm kev sib npaug thermochemical thiab kev sib npaug tshuaj yog qhov hloov pauv enthalpy ntawm cov tshuaj tiv thaiv. Cov kev sib npaug ntawm cov thermochemical ib txwm qhia txog kev hloov pauv ntawm cov tshuaj tiv thaiv, tab sis cov tshuaj sib npaug tsis feem ntau qhia qhov hloov pauv enthalpy.
