This system has an equilibrium constant of 50.5 at 448°c: h2(g) + i2(g) ↔ 2hi(g). what is the reaction quotient, q, for this system when [h2] = 0.200 m, [i2] = 0.100 m, and [hi] = 3.00 m?

Although respiratory organs vary across different organisms, they all contain respiratory surfaces that have a large surface area and are extremely thin. explain why having an extremely thin respiratory surface with a large surface area is advantageous for the process of gas exchange
