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.
A graph is shown with two graph lines sloping upwards. The title on the x axis is Time and the title on the y axis is Amount of Product. The graph line with a steeper slope is labeled Trial 2 and the other is labeled Trial 1.


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

Trial 1 has a lower concentration of the reactant because the  because the average rate of the reaction is lower.

What is a reaction?

The term reaction has to do with the combination of reactants in order to yield products. Now we know that the reaction profile is used to show the interaction that exists between the reactants and the products.

The y-axis of the graph is for the amount while the x axis of the graph is the reaction time. The rate of reaction is the time taken for a given amount of products to appear or for a given amount of reactants to disappear.

Thus, from the graph, we can see that trial 1 has a lower concentration of the reactant because the  because the average rate of the reaction is lower.
