2A(g) ⇆ B(g) sistemada jarayon o‘rtacha tezligi 3 mol/(l·min). A moddaning dastlabki miqdori 9 mol bo‘lib 30 sekunddan keyin moddalarning muvozanat konsentratsiyalari teng bo‘lsa, K_M ni hisoblang.

  1. 3/2
  2. 2/3
  3. 3/4
  4. 4/3

📝 Detailed explanation

30 s = 0,5 min. Δ[A]=3·0,5·2=3 mol/l. [A]=[B] muvozanatda; A: 9−3=6; B: 1,5. Hisob bo‘yicha K_M = [B]/[A]² ko‘rinishi, javob — 2/3.
