At a certain temperature, this reaction establishes an equilibrium with the given equilibrium constant, Kç. 3 A(g) + 2 B(g) = 4 C(g) K = 1.33 x 1021 If, at this temperature, 1.70 mol of A and 4.00 mol of B are placed in a 1.00 L container, what are the concentrations of A, B, and C at equilibrium?

Steam reforming of methane ( CHA) 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 75.0 L tank with 34. mol of methane gas and 14. mol of water vapor, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 4.2 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.

Initially, 0.1500 mol of SO3(g) were placed in a 1.00 L reaction vessel, heated to a high temperature and allowed to come to equilibrium according to the reaction 2 SO3(g) → 2 SO₂(g) + O2(g) Kc = ? It was found that the equilibrium concentration of SO₂(g) was 0.1424 M. What is the equilibrium constant, Kc, for the reaction at this temperature? A. 0.041 ✓B. 25 C. 0.064 D. 98

At a particular temperature 8.0 mol NO2 gas is placed in a 1.0-L container. Over time the NO2 decomposes to NO and O2: 2NO2(g) 2 2NO(g) + O2(g) At equilibrium the concentration of NO(g) was found to be 1.8 mol/L. Calculate the value of K for this reaction (using units of mol/L for the concentrations). K =
