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.
