PROBLEMS: Show your work at all times. Pay attention to significant digits and units. (20 marks) 26. (a) Calculate the value of the equilibrium constant for the following forwards reaction at equilibrium at 25C : given the concentration of nitrogen is 1.5mol/L, oxygen is 3.0mol/L, and nitrogen dioxide is 4.5mol/L as measured in a sealed container. ( 3 marks) (b) Does this reaction favor the forwards or reverse reaction? (1 mark) (c) If this reaction was reversed, what would happen to the equilibrium constant? Please show work to explain your answer. ( 1 mark) 27. (a) Write the balanced, reversible reaction for the synthesis of iodine monobromide (Br(g)) from its elements. (1 mark) (b) Consider the equilibrium as described by your equation above. If 4.0mol of iodide and 4.0mol of bromine were initially placed in a closed 2.0L container and allowed to reach equilibrium at 150C, what would the equilibrium concentrations be for all entities if Keq =1.2102?
