Final answer:
The direction of the reaction depends on the concentration of the substances involved.
Step-by-step explanation:
Determining the direction of the reaction
Based on the given information, we can predict the direction in which the reaction will proceed. Let's consider the balanced chemical equation: N2 + 3H2 → 2NH3. In this reaction, N2 and H2 are the reactants, while NH3 is the product.
If the equilibrium is stressed by increasing the concentration of N2 or H2, Le Chatelier's principle tells us that the reaction will shift in the forward direction to relieve the stress. This means more NH3 will be produced, and the reaction will proceed towards the products.
On the other hand, if the equilibrium is stressed by increasing the concentration of NH3, the reaction will shift in the reverse direction to relieve the stress. This means that some NH3 will be converted back into N2 and H2, and the reaction will proceed towards the reactants.
