Question

based on the particle model, which part is favored at equilibrium? graph: concentration (y-axis) vs time (t, x-axis) with curves p (blue) and r (orange); options: reactant, product

Explanation:

To determine which is favored at equilibrium, we analyze the concentration - time graph. At equilibrium (after time \(t = 4\), as indicated by the dashed line), the concentration of \(P\) (Product) is higher than the concentration of \(R\) (Reactant). In chemical equilibrium, the species with the higher concentration at equilibrium is the one that is favored. So, since the product (\(P\)) has a higher concentration at equilibrium, the product is favored.

Answer:

Product
