A.     Use your results to determineif the forward reaction in the potassium chromate/HCl reactionendothermic or exothermic. Explain your answer, using Table 1 tohelp construct your thoughts.
B.     Write the equation for theequilibrium constant (K) of the reaction studied in thisexercise.
2K2Cr4 + 2HCl ------> Cr2o7 + H2O + 2KCl
Use the information below to answer Questions C, D, andE:
The equilibrium constant (K) of the reaction below is K = 6.0 x10-2, with initial concentrations as follows:[H2] = 1.0 x 10-2 M, [N2] = 4.0 M,and [NH3] = 1.0 x 10-4M.
N2 + 3H2 ------> 2NH3
If the concentration of the reactant H2 was increasedfrom 1.0 x 10-2 M to 2.5 x 10-1M, calculatethe reaction quotient (Q) and determine which way the equilibriumposition would shift.
If the concentration of the reactant H2 was decreasedfrom 1.0 x 10-2 M to 2.7 x 10-4M, calculatethe reaction quotient (Q) and determine which way the equilibriumposition would shift.
If the concentration of the product NH3 was decreasedfrom 1.0 x 10-4 M to 5.6 x 10-3M, calculatethe reaction quotient (Q) and determine which way the equilibriumposition would shift.
