Maqolada moddalar issiqlik sig'imi temperaturaga bog'liq bo Imasligim hisobga olib, Temkin Shvarsmaiming hisob uslubi orqali kimyoviv reaksivalar tengligi amqlcmgcmligi keltirilgan.Hozirda bu uslubdan absolvut entropiyalardan foydalanib, turli haroratlarda kimyoviv reaksivalar konstantalar tengligini hisoblashda, kerakli aniq natijalarni olgan holda, keng foydalanib kelinmoqda. Bundan tashqari gidroftorlash jarayonini o'rganish ko'rib chiqilgan, turli haroratlarda texnogen tuzilishning isitish namunasiga bog'liq bo'lgan kremniy dioksidining о 'zgarish darajasi aniqlangan.

Tayanch iboralar: kimyoviv reaksiva, Temkin -Shvarsman uslubi, katta issiqlik sig'imlilik, isish temperaturasi, absolvut entropiva, kremniy dioksidining о 'zgarish darajasi, isishning о 'sishi, aktivlashish energivasi, termodinamika, kukunsifatfaza, suvning bug'lanishi, ammiakning fool ajralishi, gazli faza.

In article definitions o f balance o f chemical reaction by a calculation method o f Temkin-Schwarzman, taking into account are stated that the thermal capacity o f substances doesn't depend on temperature.Now this method is widely used when calculating constants o f balance o f chemical reactions at any temperatures with use o f absolute entropy, yielding results o f necessary accuracy. Also hydrofluorination process studying are considered, extents o f transformation o f dioxide o f silicon depending on heating o f a model o f technogenic educations at various temperatures are defined.

Key words: chemical reaction, method o f Temkin-Schwarzman, thermal capacity, preheat temperature, absolute entropy, extents o f transformation o f dioxide silicon, increase in heating, activation energy, thermodynamics, powder phase, evaporation o f water, active release o f ammonia, gaseous phase.
