Kimyoviy reaksiyaga kirishish tezligi
EMBED Equation.3 funksiya bilan vaqtning EMBED Equation.3 onida reaksiyaga kirishuvchi kimyoviy modda miqdori aniqlanayotgan bo‘lsin. Bunda EMBED Equation.3 vaqtning EMBED Equation.3 orttirmasiga EMBED Equation.3 kattalikning EMBED Equation.3 orttirmasi mos keladi va EMBED Equation.3 nisbat EMBED Equation.3 vaqt oralig‘ida kimyoviy reaksiyaning o‘rtacha tezligini ifodalaydi. Bu nisbatning EMBED Equation.3 nolga intilganidagi limiti, ya’ni
EMBED Equation.3 yoki EMBED Equation.3
kimyoviy moddaning EMBED Equation.3 ondagi reaksiyaga kirishish tezligini aniqlaydi.
Tabiatning turli sohalariga tegishli ko‘plab masalalari (6.1) - 6.3) ko‘ri-nishdagi limitlarni topishga olib keladi. Masalan, agar EMBED Equation.3 vaqtning EMBED Equation.3 onida tabletkadagi dori moddasining miqdori bo‘lsa, u holda dori moddasining EMBED Equation.3 ondagi erishi tezligi
EMBED Equation.3
tenglik bilan aniqlanadi.
Egri chiziqqa o‘tkazilgan urinma va normal tenglamalari
EMBED Equation.3 funksiya bilan aniqlangan egri chiziqqa EMBED Equation.3 (bu yerda EMBED Equation.3 ) nuqtada o‘tkazilgan urinma tenglamasini hosilaning geometrik ma’nosidan keltirib chiqaramiz.
Urinma EMBED Equation.3 nuqtadan o‘tadi. Shu sababli uning tenglamasini EMBED Equation.3 ko‘rinishda izlaymiz. Hosilaning geometrik ma’nosiga ko‘ra
EMBED Equation.3 .
Bundan
EMBED Equation.3 (7)
urinma tenglamasi kelib chiqadi.
Egri chiziqqa o’tkazilgan normal deb, urinish nuqtasida urinmaga perpendikulyar bo‘lgan to‘g‘ri chiziqqa aytiladi.
Egri chiziqqa EMBED Equation.3 nuqtada o‘tkazilgan normal shu nuqtada o‘tkazilgan urinmaga perpendikulyar bo‘lgani sababli
EMBED Equation.3 .
Bundan
EMBED Equation.3 (8)
normal tenglamasi kelib chiqadi (agar EMBED Equation.3 bo‘lsa).
