Hydrogen and iodine gas react to produce hydrogen iodide gas. What is the value of Keq for this reaction if at equilibrium the concentration of H2, I2 and HI were 0.25M, 0.035M, and 0.55M respectively?

Use the References to access important values if needed for this question. In an aqueous solution of a weak acid, HA, the assumption is often made that [HA]equilibrium = [HA]nitial: This approximation is reasonable if the initial concentration of the acid is sufficiently large compared to Ka. What multiple of K, must the initial concentration of a weak acid exceed, for the initial concentration and the equilibrium concentration to be within 9.98 percent of each other?

Steam reforming of methane ( CH ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. An industrial chemist studying this reaction fills a 25.0 L tank with 7.0 mol of methane gas and 1.8 mol of water vapor, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 1.4 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits. K = || %3D Submit Assignn

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. An industrial chemist studying this reaction fills a 50.0 L tank with 22. mol of sulfur dioxide gas and 4.2 mol of oxygen gas, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 5.9 mol. Calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. Round your answer to 2 significant digits.

Indicate the equilibrium shift, right or left, when the accompanying stress is applied to the system.  Explain the reason for the shift. 1) Na2S(aq) is added to AgI(s)---Ag+(aq) + I-(aq) 2) KOH(aq) is added to CH3COOH(aq) + H2O(l)--- H3O+(aq)+ CH3CO2-(aq) 3) HCl(aq) is added to 4Cl-(aq)+Co(H2O)62+(aq)---CoCl42-(aq) + 6H2O(l)

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 25.0 L tank with 5.3 mol of ammonia gas and 2.4 mol of oxygen gas, and when the mixture has come to equilibrium measures the amount of nitrogen gas to be 1.4 mol. Calculate the concentration equilibrium constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits. K = -0 ☐ x10 G

If BaCO3 is placed in an evacuated flask, what partial pressure will be present when the reaction reaches equilibrium?

Steam reforming of methane ( CH ) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. An industrial chemist studying this reaction fills a 25.0 L tank with 1.8 mol of methane gas and 6.0 mol of water vapor, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 0.18 mol.
