Equilibrium Constant Calculations

Concept #1: Equilibrium Constant Calculations Concept 1

Practice: The reaction: 2 NO(g) + Br2(g) ⇌ 2 NOBr(g), has a Kp of 2.5 x 102 at 35°C. Calculate the equilibrium concentration of NOBr, if equilibrium concentrations of NO and Br2 are 0.2 atm and 0.050 atm, respectively.

Practice: For the reaction below, Kc = 1.5 at a constant temperature. A 3.2 L flask contains an equilibrium mixture of 3 compounds: 3.7 g of NH4HS, 70. g of NH3 and unknown amount of H2S. What is the mass (grams) of H2S produced at equilibrium?

NH4HS(s) ⇌ NH3(g) + H2S(g)
