Problem #1 Consider the following reaction at 201 K: 1A (aq) + 1 B (aq) - 2 C (aq) + 1D (aq) An experiment was performed with the following intitial concentrations: [A]j = 1.25 M, [B]; = 2.17 M, [C] = 0.33 M, [D] = 0.27 M. The reaction was allowed to proceed until equilibrium was reached at which time it was determined that [A] = 0.61 M. What was the maximum amount of work that could have been performed as the reaction began? Maximum amount of work performed as the reaction began (in kJ) =

Problem #1 Consider the following reaction at 201 K: 1 A (aq) + 1 B (ag) - 2 C (aq) + 1 D (ag) An experiment was performed with the following intitial concentrations: [A]; = 1.25 M, [B]; = 2.17 M, [C]; = 0.33 M, [D]; = 0.27 M. The reaction was allowed to proceed until equilibrium was reached at which time it was determined that [A] = 0.61 M. What was the maximum amount of work that could have been performed as the reaction began? Maximum amount of work performed as the reaction began (in k)= Problem #2 Consider the following reaction at 239 K: 2 Cu,o (s) – 4 Cu (s) + 02 (g) In one of your laboratory experiments, you determine the equilibrium constant for this process, at 239 K, is 2.964E-67. You are given a table data that indicates the standard heat of formation (AH°form) of Cu20 is -170 kJ/mol. Based on this information, what is the standard entropy change (AS°rvn) for this reaction at 239 K? AS°nen(3/K)= | Problem #3 Consider the following reaction: A (aq) - B (aq) AG°pen 4.33 k) A reaction vessel was charged with compound A (3.31 M) and compound B (6.51 M) and allowed to react at 193 K. After a period of 5.5 hours, AG was determined to be 3.71 k). What was the concentration of compound A at that time? [A] =
