I Am Performing a Reaction,A B,with DG° = -5000 KJ/mol

question 30

Multiple Choice

I am performing a reaction,A B,with DG° = -5000 kJ/mol.I start the reaction with 10 mM A and no B. After allowing the reaction to proceed for 24 hrs at room temperature and atmospheric pressure,I analyze a sample of the reaction mix to find I now have 8 mM A and 2 mM B.Which of the following conclusions should I make?

• A)The reaction has reached equilibrium.
• B)I should come back again later; equilibrium has not yet been reached.
• C)The formation of B from A is thermodynamically unfavorable,so I should find another starting material to make B.
• D)I must've screwed up; there's no way I could get that result with that D°
