Q=1.6 * 10 (-10 exponent)
D. If the concentration of the reactant H2 was decreased from 1.0 x 10-2 M to 2.7 x 10-4M, calculate the reaction quotient (Q) and determine which way the equilibrium position would shift.
Q=1.270131585632272 * 10 (2 exponent) It will shift left.
E. If the concentration of the product NH3 was decreased from 1.0 x 10-4 M to 5.6 x 10-3M, calculate the reaction quotient (Q) and determine which way the equilibrium position would shift.
Q=7.84 * 10(-4 exponent). It will shift right.
Exercise 2: Equilibrium of Ferrocyanide and Ferric Ferrocyanide
Data Table 3. Ferric Ferrocyanide.
Color of Potassium Ferrocyanide
Color of Ferric Ferrocyanide
Number of drops of NaOH to shift equilibrium position
Observations when equilibrium position is shifted
Light yellow
Dark blue/greenish
4 drops
The dark blue/greenish substance turned brown while the surrounding substance turned yellow.
Questions
A. From your observations and data collected in Data Table 3, describe the direction of the equilibrium position shift upon addition of NaOH.
The equilibrium position would shift left because the product ratio increases when NaOH is added.
