(Incorrect) 2 H₂S(g) + 2 H₂(g) + S₂(g) Kc = 9.3x 108 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 x 10-3 M 2.7 x 10-8 M 3.2 × 10-4 M 6.3 x 10-3 M (Correct answer)

Answer the question please.

Consider the following reaction: 2CO (g) + O2 (g) ⇒ 2CO2 (g). In a 2.00 L vessel, 0.5 moles of carbon monoxide gas reacts with 0.5 moles of oxygen gas. Given that K = 2.2 × 10-22, what are the concentrations of all species at equilibrium? The concentration of CO at equilibrium is The concentration of O2 at equilibrium is The concentration of CO2 at equilibrium is

Select all of the correct statements about equilibrium from the choices below.At equilibrium the rates of forward and reverse reactions are equal. As a reaction proceeds forward toward equilibrium the forward rate drops. At equilibrium all reactions stop.   Reactants are transformed into products even at equilibrium.   As a reaction proceeds forward toward equilibrium the reverse rate constant rises.As a reaction proceeds forward toward equilibrium the forward rate constant drops.
