Question

If the chemist that prepared the stock solutions used in this experiment made an error prepared a 0.020 M stock solution of KSCN and incorrectly labeled it as the 0.002 M solution you used today how would this affect the average value of the equilibrium constant determined in this experiment? Explain why it would increase, decrease or have no effect on the value. If the value of e determined in the prelaboratory calculation was larger than the true value due to a miscalculation, how would this affect the average value of the equilibrium constant determined in this experiment? Explain why it would increase decrease or have, . no effect on the value.

Explanation / Answer

1. Equilibrium constant does not depend upon the concentration. It depends on the ratio of reactant ad products and thus we would not see any change in this case.

2. If the value of e calculated was larger than true value. Concentration of complex would be lower as caluclated and concentration of reactants would be higher. The average value for equilibrium constant would be lower than actual value.
