You're on a roll — Here are the detailed solutions for the reactions from the image: *a) For the reaction N_2(g) + 2O_2(g) 2NO_2(g): Step 1: Identify reactants and products with their stoichiometric coefficients. Reactants: N_2 (coefficient 1), O_2 (coefficient 2). Products: NO_2 (coefficient 2). Step 2: Apply the equilibrium constant expression formula. The concentration of products raised to their stoichiometric coefficients goes in the numerator, and the concentration of reactants raised to their stoichiometric coefficients goes in the denominator. K_c = [NO_2]^2[N_2]^1[O_2]^2 Step 3: Simplify the expression. K_c = [NO_2]^2[N_2][O_2]^2 *b) For the reaction 2N_2(g) + O_2(g) 2N_2O(g): Step 1: Identify reactants and products with their stoichiometric coefficients. Reactants: N_2 (coefficient 2), O_2 (coefficient 1). Products: N_2O (coefficient 2). Step 2: Apply the equilibrium constant expression formula. K_c = [N_2O]^2[N_2]^2[O_2]^1 Step 3: Simplify the expression. K_c = [N_2O]^2[N_2]^2[O_2] *c) For the reaction 2SO_2(g) + O_2(g) 2SO_3(g): Step 1: Identify reactants and products with their stoichiometric coefficients. Reactants: SO_2 (coefficient 2), O_2 (coefficient 1). Products: SO_3 (coefficient 2). Step 2: Apply the equilibrium constant expression formula. K_c = [SO_3]^2[SO_2]^2[O_2]^1 Step 3: Simplify the expression. K_c = [SO_3]^2[SO_2]^2[O_2] *d) For the reaction PCl_3(g) + Cl_2(g) PCl_5(g): Step 1: Identify reactants and products with their stoichiometric coefficients. Reactants: PCl_3 (coefficient 1), Cl_2 (coefficient 1). Products: PCl_5 (coefficient 1). Step 2: Apply the equilibrium constant expression formula. K_c = [PCl_5]^1[PCl_3]^1[Cl_2]^1 Step 3: Simplify the expression. K_c = [PCl_5][PCl_3][Cl_2] Drop the next question!
