Waxyaabaha saameeya heerka of reaction kiimikada

Iyada oo fikirka ah "xawaaraha" inta badan kala kulantay koorsada of physics. Qeexidda guud ee xawaaraha waa qiime kaas oo ay muujinaysaa sida ay badala sifo kasta halkii unit of time.

qeexitaanka "heerka reaction kiimikada." The chemistry isticmaalo Qaybtan waxaa go'aaminaya inta ay le'eg tahay halkii mar unit kala duwan fiirsashada bilaabo reagents ama waxyaabaha reaction helay.

In la qiyaaso heerka, beddelo-fiirsashada ee mid ka mid ah maadooyinka.

The hababka ugu xiisaha badan jawi dhqaalaha. Dhqaalaha (uniform) nidaamyada waa dareere ama gaasas. Waxyeellada waxaa ka dhacay buuxa. Heerka kiimikada reaction nidaam sida beddelo ratio fiirsashada waxaa loo xisaabiyaa oo bareeg ah waqtiga lagu jiro taas oo dareen-celinta ay taasi dhacdo.

Non-dhqaalaha (Nuurre Aw) ee nidaamka waa sida soo socota: adag - gaaska, adag - dareere ah iyo gaaska - dareere ah. In nidaamka reaction dhacaan at dusha soohdinta wajiga. Heerka falgalka kiimikada ee nidaamka Nuurre Aw loo ogaado tirada jiirarka walxaha taas oo ay galeen ama la aasaasay by tiriska unit dusha halkii mar unit.

Waxyaabaha saameeya heerka of reaction kiimikada

Saameyn waxqabadka ee fiirsashada of walxaha, heerkulka, joogitaanka a Hannaan (inhibitor), meesha xiriir iyo dabeecadda oo ka mid ah sinji.

First, heerka reaction kiimikada ku xiran yahay fiirsashada ee reactants ah. Waxaa koraa saamiga si toos ah wax soo saarka ah ee ay isugu soo urureen oo ay. Sababta sii kordhaya tiro xawaaraha sii kordheysa ee reagents ah u dhaqmo shilalka walxaha ay sabab u kordhin lahaayeen tirada halkii mugga unit.

Kordhinta heerka socodka geedi socodka kiimikada ku kordhinaya koror ah ee heerkulka. The falgalka kiimikada ka dhacaya nidaamka dhqaalaha (xal dareere ah, isku gaaska) dhacaan sabab u ah shilalka ka mid ah qaybaha (qayb). Si kastaba ha ahaatee, mar walba ha ku dagaallamay reagents keenaysaa in waxyaabaha cusub. Kaliya qayb firfircoon oo kordhay tamarta, oo awood u leh fulinta reaction kiimikada.

Iyada oo sii kordhaya heerkulka kordhiyaa tamarta ogeed of noocyada kiimikada iyo tirada noocyada firfircoon sidoo kale waxay kordhisaa. Sidaa darteed, falcelinta ka dhici doona marka heerkulku sare ka badan at hooseeyo. Sii go'aanso sida heerka falcelinta ku xiran tahay heerkulka, guud ahaan ogolaanaya van't Hoff. postulate in sida korodhka heerkulka toban kasta degrees Celsius ah, heerka reaction kiimikada waxaa kordhay 3-4 jeer. Si kastaba ha ahaatee, tani guud ahaan ku siinaysaa qiimaha saxda ah, iyo waxa loo isticmaalaa oo kaliya wacyi gelin qiimayn hore ee saameyna ku leh heerkulka.

saameyn weyn xawaaraha of falcelinta Eebay joogitaanka Hannaan - walax oo dedejiya nidaamka kiimikada. Xoojiya ula falgalaan reagents ah si ay u sameeyaan kiimiko dhexe, iyo in dhammaadka falcelinta waxay lagu sii daayo. Sida laga soo xigtay state of xulkii kala saaro Xoojiya dhqaalaha iyo Nuurre Aw.

Walxaha in la xakameeyo falcelinta, la yiraahdo celiyeyaasha.

heerka falcelinta sidoo kale waxay ku xiran tahay meesha wadajirka ah ee xiriirka ee reactants ah. Si loo kordhiyo sifo this, walax la milled. Heerka ugu badan ee comminution waxaa lagu gaarayaa by kala diridda reagents ah. Sidaa darteed, dhibaatooyinka ugu dhaqsiyaha badan ka dhacaan xal.

reactants Nature sidoo kale saamaysaa heerka falcelinta. Tusaale ahaan, birta iyo magnesium leeyihiin xawaare ka duwan dhexgalka la-fiirsashada isku mid ah acids. Tan waxa u sabab waxqabadka kiimikada kala duwan ee biraha kuwan.
