B)The amount of product is greater than the amount of reactant.
C) The reaction uses all its reactants to form products.
D) The reaction reaches equlibrium at 1.5 seconds
E) The amount of reactants is highest at equilibrium.

Answer 1

The inference from the graph of a chemical reaction between A and B showing decreasing reactant concentration and increasing product concentration is that the reaction slows down over time as reactants are consumed, which is consistent with the Law of Mass Action.

Step-by-step explanation:

An inference that can be drawn from the given graph, which shows the progress of a chemical reaction over time between reactants A and B forming products, is that the amount of reactant A decreases while the amount of product B increases. Since reaction rates are typically highest when reactant concentrations are highest, we would expect the reaction to start rapidly and slow down as the reactants are consumed. This aligns with the Law of Mass Action, which states that reaction rates are generally greater at higher reactant concentrations due to more frequent and effective collisions. Over time, if there is no further change in the concentrations of A and B, it implies that equilibrium has been reached, characterized by the equal rate of the forward and reverse reactions.
