Question

The graph shows the amount of a gaseous product formed over time during two trials of a reaction. A different concentration of a reactant was used during each trial while other factors were kept constant.Which of the following statements explains which trial has a higher concentration of the reactant? Trial 1, because the final amount of product formed is higher. Trial 1, because this reaction lasted for a longer duration than Trial 2. Trial 2, because this reaction was initially fast and slowed down later. Trial 2, because the amount of product formed per unit time is higher.

Answer 1

In this question, we have two trials, and we need to decide, based on the graph, which of the reactions has a higher concentration of reactant, and by analyzing the graph, we can see that the trial 2 has a higher amount of volume of product per unit of time, making it also the higher on the value of reactants. Therefore the best answer will be the last answer " Trial 2, because the amount of product formed per unit time is higher"
