What is a Chemical reaction?
Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.
When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases
Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.
