1. At equilibrium, a mixture of N, H2, and NH, gas at 500°C is determined to consist of 0.602 mol/L of N,, 0.420 mol/L of H2, and 0.113 mol/L of NH3. What is the equilibriur
constant for the reaction N2(g) + 3H2(g) = 2NH() at this temperature?

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
