I- variant
1. Hajmi 2 l bo’lgan idishda 4,5 mol modda miqdori 20 s o’tgandan keyin, 2,5 mollgacha kamaysa, reaksiya tezligi (Mol, l, s) da qanday bo’ladi.
2. Ammiakning katalitik oksidlanishi natijasida 4 NH3 + 5O2 4NO + 6 H2O ushb reaksiyada bosim 2 marta oshirilsa to’g’ri reaksiya tezligi necha marta ortadi.
3 Tiosulfat kislotani parchalanish reaksiyasi 30°C da 30 sek da tugaydi. Shu reaksiya 50°C da necha sek da tugaydi? = 2
4. 2. 60 °C da 2CO(g)+ O2(g) ↔ 2CO2(g)ushbu sistemaning to‘g‘ri reaksiya tezligi 3 mol/l·minga teng. Agar shu reaksiyaning harorat koeffitsiyenti 3 ga teng bo‘lsa, 90 °C dagi reaksiya tezligini (mol/litr·min) aniqlang.
5. SO + Cl2 = SOCl2 sistemasida is gazining konsentrasiyasi 0,03 dan 0,12 mol/l ga qadar, xlorning konsentrasiyasi 0,02 dan 0,06 mol/l ga qadar oshirilgan. Reaksiya tezligi necha marta ortganligini aniqlang?
