2A2 (g) + B2 (g) ⇌ 2A2B (g) বিক্রিয়ায় সাম্যবস্থায় ঘনমাত্রার মান যথাক্রমে [A2] =0.5mol/L [B2]=0.1mol/L এবং [A2B] = 2mol/L হলে সাম্যধ্রুবক Kc কত একক?

Chemical Equilibrium Calculation 🧪

Given reaction: \(2A_2(g) + B_2(g) \rightleftharpoons 2A_2B(g)\)

Equilibrium concentrations:

• \([A_2] = 0.5 \, \text{mol/L}\)
• \([B_2] = 0.1 \, \text{mol/L}\)
• \([A_2B] = 2 \, \text{mol/L}\)

The equilibrium constant \(K_c\) for the reaction is given by:

\(K_c = \frac{[A_2B]^2}{[A_2]^2 [B_2]}\)

Substituting the given values: \(K_c = \frac{(2)^2}{(0.5)^2 (0.1)} = \frac{4}{0.25 \times 0.1} = \frac{4}{0.025} = 160\)

Therefore, the equilibrium constant \(K_c\) is 160. 🎉
