Unformatted text preview: 3. If 1.2x10-3 M HBr is allowed to react at 500K, what is the percentage of decomposition of HBr and what is the equilibrium composition of each reactant and product? 2HBr (g) H 2 (g) + Br 2 (g) K = 7.7x10-11 at 500K 4. 0.0240 moles of N 2 O 4 is allowed to come to equilibrium with NO 2 in a 0.372L flask at 25 o C. What is the equilibrium concentration of each at room temperature? N 2 O 4 (g) 2 NO 2 (g) K = 4.61x10-3 at 25 o C,...
