(Incorrect) 2 H₂S(g) + 2 H₂(g) + S₂(g) Kc = 9.3x 10-8 at 400°C 3.5 moles of H₂S are placed in a 3.0 L container and the system is allowed to reach equilibrium. Calculate the concentration of H₂ at equilibrium. 3.1 x 10-3 M (Your answer) 4.8 × 10-3 M 2.7 x 10-8 M 3.2 × 10-4 M 6.3 × 10-3 M (Correct answer)

For the equilibrium: A  ↔  B, if [A]o = 0.162, [B]o = 0.569, and Keq = 47.8, what are [A]eq and [B]eq? Only show the algebraic expression with final [A]eq and [B]eq

Incorrect Row 2: Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. A chemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 NO(g) + Cl,(g)=2 NOCI(g) -9- K,=4. × 10 He fills a reaction vessel at this temperature with 11. atm of nitrogen monoxide gas and 9.8 atm of chlorine gas. Use this data to answer the questions in the table below. Answer Submitted: olo O yes Can you predict the equilibrium pressure of NOCI, using only the tools available to you within ALEKS? no If you said yes, then enter the equilibrium pressure of NOC1 at right. Round your answer to 1 significant digit. 0.1 atm
