For the system A(g) + 2B(g) C(g),the equilibrium — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

I notice your question appears incomplete — "the equilibrium..." is cut off, and option A isn't shown. However, I can provide a framework for solving equilibrium problems for this reaction: $$A(g) + 2B(g) \rightleftharpoons C(g)$$ **General approach:** 1. **Write the equilibrium constant expression:** $$K_c = \frac{[C]}{[A][B]^2}$$ 2. **For Le Chatelier's principle questions:** Identify the stress (pressure, temperature, concentration change) and predict the shift direction. 3. **For numerical problems:** Use an ICE table: - **I**nitial concentrations - **C**hange (using stoichiometry) - **E**quilibrium concentrations - Substitute into $K_c$ expression 4. **For pressure effects:** Since 3 moles of gas (1A + 2B) → 1 mole of gas (C), increasing pressure shifts **right** (toward fewer moles). 5. **For temperature:** Direction depends on whether reaction is exo- or endothermic. **To verify your answer is correct:** Please share the complete question options, and I'll explain specifically why A is right and others are wrong.
