E.
The reaction between A and B is reactant favored
The amount of product is greater than the amount of reactant
The reaction uses all its reactants to form products
The reaction reaches equilibrium of 1.5 seconds
The amount of reactants is highest at equilibrium

Answer 1

Based on the given graph, the correct inference that can be drawn is:

E. The amount of reactants is highest at equilibrium.

This inference is supported by the graph's shape, which shows a decreasing trend in the concentration of reactants (A and B) over time until it reaches a point of equilibrium. At equilibrium, the concentration of reactants remains constant, indicating that the amount of reactants is highest at that point.
