1. SO_(g)+N₂O_(g)=SO_2(g)+N_2(g) reaksiyaning muvozanat konstantasi 850⁰S da 1 ga teng. SO va N₂O ning boshlang‘ich konsentratsiyalari 2 va 3 mol/l bo‘lsa, SO₂ ning muvozanat holatdagi konsentratsiyasini (mol/l) aniqlang.

2. SO_2(g)+N_2(g)=SO_(g)+N₂O _(g) reaksiyaning konstantasi 850⁰S da 1 ga teng. SO₂ va N₂ ning boshlang‘ich konsentratsiyalari mos ravishda 6 va 8 mol/l bo‘lsa, ularning muvozanat holatdagi konsentratsiyalarini (mol/l) aniqlang.

3. 1. NH3+O2=N2O+N2reaksiyada kimyoviy muvozanat qaror topganda moddalar konsentratsiyalari [NN3]=0,4; [O2]=0,65; [N2O]=0,3 mol/litr ni tashkil qiladi. Reaksiya hajmi 0,005 m³ bo‘lgan idishda olib borilgan bo‘lsa, dastlabki moddalar miqdorini (mol) hisoblang.

4. 3. 3A+B=C+2D reaksiya bo‘yicha muvozanat qaror topgandan so‘ng moddalarning muvozanat konsentratsiyalari quyidagicha: [A]=0,1 mol/l, [B]=0,5 mol/l, [C]=0,03 mol/l, [D]=0,4 mol/l bo‘lsa, muvozanat konstantasini aniqlang.
