Suppose that for the reaction K + L → M, you monitor the production of M over time, and then plot the following graph from your data:
Graph showing the concentration of M over time, indicating reaction progress for K + L → M.
(b) Is the reaction completed at t = 15 min? [Section 14.2]

Observe the graph showing the concentration of M over time.
Note that the concentration of M increases linearly from 0 to 30 minutes.
At 30 minutes, the concentration of M levels off and remains constant.
Determine if the reaction is complete by checking if the concentration of M changes after 15 minutes.
Since the concentration of M continues to increase after 15 minutes and only levels off at 30 minutes, the reaction is not complete at t = 15 min.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Reaction Completion

A chemical reaction is considered complete when the concentration of the products no longer changes over time. In the context of the provided graph, this means that if the concentration of M remains constant after a certain time, the reaction has reached completion.

Rate of Reaction

The rate of a chemical reaction refers to how quickly reactants are converted into products. This can be observed in the graph as the slope of the line representing the concentration of M over time. A steeper slope indicates a faster reaction rate, while a flat line indicates that the reaction has slowed or stopped.

Equilibrium

Chemical equilibrium occurs when the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products. In the graph, if the concentration of M stabilizes at a certain level, it suggests that the system may have reached equilibrium, indicating that the reaction is no longer proceeding in either direction.
