Consider the following exothermic reaction at equilibrium:
2SO2 (g) + O2 (g) ⇌ 2SO3 (g) ΔH° = –99 kJ/molLe Châtelier's principle predicts that an increase in temperature at constant pressure will result in ________.
Nitrosyl bromide decomposes according to the following equation:2NOBr (g) ⇌ 2NO (g) + Br2 (g) A sample of NOBr (0.721 mol) was placed in an empty 1.00 L flask. At equilibrium the flask contained 0.177 mol of NOBr. How many moles of NO are in the flask at equilibrium?
Dinitrogentetraoxide partially decomposes according to the following equilibrium:
N2O4 (g) ⇌ 2NO2 (g) A 1.00 L flask is charged with 0.0400 mol of N2O4 at 373 K. An equilibrium is established after some time and only 0.0055 mol of N2O4 remains. What is KC for this reaction?
