Nazorat ishi- 5
II- variant
1. Hajmi 5 l bo’lgan reaktorda reaksiya borishi natijasida 30 sekund davomida konsentrasiyasi 6,8 molldan 3,4 mollgacha kamaysa, shu reaksiya tezligi (Mol, l, s) da qanday bo’ladi.
2. Quyidagi sistemada CH4 + 2 O2 CO2+ 2 H2O metan gazining konsentrasiyasi 3 marta va kislorod konsentrasiyasi ikki marta oshirilsa to’g’ri reaksiya tezligi necha marta otadi.
3 = 2 bo’lgan reaksiyani 20°C da tugatish uchun 2 soat ketadi. Shu reaksiyani 0,5 soatda tugatish uchun xaroratni necha ○C ga ko’tarish kerak?
4. Agar is gazining yonish reaksiyasining tezligi 33 °C da 0,5 mol/l·min ga teng bo‘lsa, 53 °C haroratdagi reaksiya tezligini(mol/litr·min) aniqlang. Reaksiyaning temperatura koeffitsiyenti 4 ga teng.
5.5 = 2 bo’lgan reaksiyani 30◦S da tugatish uchun 3 soat ketadi, shu reaksiyani 45 minutda tugatish uchun xaroratni necha ◦S ga ko’tarish kerak?
