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?
