. In the diagram, the black line represents the concentration of a reactant and the green line represents the concentration of a product. Which of the following statements best describes the reaction rate?


(Points : 3)
at the end of the reaction, both product and reactants are of a constant concentration
the reactants maintain a constant concentration in the first half of the reaction
at the end of the reaction, both product and reactants are of an equal concentration
the product maintains a constant concentration in the first half of the reaction

Answer 2

This is exercise is supposed to teach you how to read graphs. On the bottom is time, on the vertical axis is concentration.

Answer 3

I think the answer is c

Answer 4

hmm they're not in equal concentrations, equal would look like this

the answer is "at the end of the reaction, both product and reactants are of a constant concentration"

Their concentrations don't change, but they're not the same
