Module 6 Lesson 3 Mastery Assignment Reaction Prediction

Module 12 Lesson 2 Mastery Assignment: Equilibrium1. Write the equilibrium expressions for the following reactions:a) 2 N2O(g) + O2(g) 4 NO(g)Kc = [NO]⁴ / ([N₂O]² [O₂])b) H2(g) + CO2(g) H2O(g) + CO(g)Kc = [H₂O] [CO] / ([H₂] [CO₂])c) 4 HCl(g) + O2(g) 2 Cl2(g) + 2 H2O(g)Kc = [Cl₂]² [H₂O]² / ([HCl]⁴ [O₂])d) 3 H2(g) + N2(g) 2 NH3(g)Kc = [NH₃]² / ([H₂]³ [N₂])e) H2(g) + Cl2(g) 2HCl(g)Kc = [HCl]² / ([H₂] [Cl₂])f)2 SO2(g) + O2(g) 2 SO3(g)Kc = [SO₃]² / ([SO₂]² [O₂])2. Using the above equilibrium expressions, calculate the equilibrium constant, K, for the following concentrations:a) [N2O] = 0.0035 M, [O2] = 0.0027 M, [NO] = 5.6 x 10-9MKc = (5.6 × 10⁻⁹)⁴ / (0.0035² × 0.0027) = 2.97 × 10⁻²⁶
