- For the reaction 2 CH4 (g) → C2H6 (g) + H2 (g)at 3547 K, Kc = 0.0235.a) If the initial concentration of CH4 is 0.535 M and there is initially no C2H6 or H2, what will the concentrations of each species be at equilibrium?Hemoglobin (Hb) and oxygen gas form a complex (HbO2) that carries oxygen throughoutthe human body. Unfortunately, carbon monoxide binds to hemoglobin so strongly that itdisplaces the oxygen already bonded there by the below equilibrium reaction:HbO2 + CO ⇌ HbCO + O2Thus, CO is toxic by reducing the concentration of HbO2 in the blood. Using the principles ofequilibrium, explain how the following first aid treatments for carbon monoxide poisoning mighthelp restore the HbO2 concentration.a. Removing the victim to an area with a safe (lower) amount of CO.b. Administering oxygen.Some sulfuric acid is spilled on a lab bench. You can neutralizethe acid by sprinkling sodium bicarbonate on it and thenmopping up the resulting solution.

- We have a hot tub that uses ozone (O3) gas as a disinfectant. The ozone generatorbubbles ozone in the water and it has a concentration of 2 mg/L of dissolved ozone in the water. I’mconcerned that the headspace above the water will have a high concentration of ozone which can behazardous. For example, OSHA states that the maximum permissible exposure is 0.2 ppmv for a 2hour exposure. Will the equilibrium ozone concentration in the headspace above the water exceedthis limit? The Henry’s Law constant for ozone is:O3(g) ↔ O3(aq) KH = 9.4 x 10-3 mol/L-atmGiven: 2 IBr(g) <=====> I2(g) + Br2(g) Suppose that 0.25M IBr in a flask is allowed to reach equilibrium at 150oC.
