REAKSIYaHOI BARGARDANDA VA BARNAGARDANDA

REAKSIYaHOI  BARGARDANDA  VA  BARNAGARDANDA, yak navi reaksiyahoi khimiyavist. Reaksiyahoe, ki samti jarayonashon ba konsentrasiyai moddaho vobasta ast, reaksiyahoi bargardanda nomida meshavand. Masalan, hangomi reaksiyai kataliziyu geterogenii bayni nitrogen va gidrogen (ZN₂ + N-2 *=* 214N₃) dar mavridi dar omekhtai gazi kam budani konsentrasiyai NN3 va ziyodii konsentrasiyahoi gidrogenu nitrogen reaksiya ba tarafi rost (hosilshavii ammiak) mayl mekunad. Dar surati ziyod budani konsentrasiyai 14N₃ reaksiya ba tarafi chap mayl menamoyad. Alomati barobari ( = ) dar chunin reaksiyaho ba alomati bargardandagi (***) ivaz meshavad. Tirchai bolo samti rost va tirchai poyon ravishi chapi reaksiyaro nishon medihad.

Dar intihoi reaksiyai bargardanda, yane hangomi ba holati muvozinati khimiyavi rasidani sistema, dar on miqdori moddahoi avvala va hosila barobar meshavad.

Reaksiyae, ki on faqat ba yak samt jarayon megiradu moddahoi avvala purra ba mahsuloti reaksiya tabdil meyoband, reaksiyai barnagardanda nomida meshavad. Masalan , reaksiyai tajziyai namaki bertole namunai reaksiyai barnagardanda meboshad: 2KS10z-*-2KS1 + E0₃ Vobasta ba sharoit, harorat, fishor, reaksiyai muayyani khimiyavi ham bargardanda va ham barnagardanda shuda metavonad.
