Answer
Q = 0.031
The mixture is at equilibrium.
Work Step by Step
1. The exponent of each concentration is equal to its balance coefficient.
$$Q = \frac{[Products]}{[Reactants]} = \frac{[ aconitate ]}{[ citrate ]}$$
2. Substitute the values and calculate the quocient value:
$$Q= \frac{( 4.0 \times 10^{-5} )}{( 0.00128 )} = 0.031$$
Q = K:
The mixture is at equilibrium.
