Answer
a. Since $1 \times 10^{-30} \lt \lt 1$, the equilibrium mixture contains mostly reactants.
b. Since $2.0 \times 10^{19} \gt \gt 1$, the equilibrium mixture contains mostly products.
Work Step by Step
- If $K_c \gt\gt 1$, the equilibrium mixture contains mostly products.
- If $K_c \lt\lt 1$, the equilibrium mixture contains mostly reactants.
- If $K_c \approx 1$, the equilibrium mixture contains similar amounts of reactants and products.
