A chemistry student needs to calculate the equilibrium constant for the following reaction:2 H2O(g) ⇌ 2 H2(g) + O2(g)The student has the initial concentration of H2 and O2 as 0.25 M and the initial concentration of H2O as 1.00 M. After the system reaches equilibrium, the student measures the concentration of H2 as 0.10 M. Using this information, what is the value of the equilibrium constant, Kc, for the above reaction?

A chemist mixes 0.1 mol of hydrogen (H2) with 0.2 mol of nitrogen (N2) in a 2 L flask at 400°C. The reaction H2(g) + N2(g) ⇌ 2NH3(g) establishes equilibrium. Calculate the equilibrium concentrations of hydrogen, nitrogen, and ammonia if the Kc value of the reaction at this temperature is 1.5 x 10^-2.
