Question

based on the particle model, which part is favored at equilibrium? graph: concentration (y - axis), time (t) (x - axis with 0, 1, 2, 3, 4, 5). curve r (green) starts high, decreases, then levels off at time 4. curve p (blue) starts at 0, increases, then levels off at time 4. options: reactant, product

Explanation:

To determine which is favored at equilibrium, we analyze the concentration - time graph. At equilibrium (around time \(t = 4\)), the concentration of the reactant (represented by \(R\)) is higher than the concentration of the product (represented by \(P\)). In chemical equilibrium, the species with the higher concentration at equilibrium is the one that is favored. So, the reactant is favored.

Answer:

Reactant
