In which case does the reaction go farthest to completion: `K=1, K=10^(-10)`, and why?

Explanation

To determine in which case the reaction goes farthest to completion between \( K = 1 \) and \( K = 10^{-10} \), we can analyze the meaning of the equilibrium constant \( K \) and its implications for the extent of the reaction.

### Step-by-Step Solution:

1. **Understanding the Equilibrium Constant (K)**:
The equilibrium constant \( K \) is defined as the ratio of the concentration of products to the concentration of reactants at equilibrium. It is given by the formula:
\[
K = \frac{[\text{Products}]}{[\text{Reactants}]}
