14.1 Define chemical equilibrium. Concentrations of reactants and products remain constant. A chemical equilibrium is “dynamic”. What does this indicate? Reactants and products continue to form. An equilibrium exists because forward and reverse reactions occur at equal rates. How are equilibrium reactions written differently than other chemical reactions? They are written with instead of . For example: Chemical reaction: A + B C Equilibrium reaction: A + B C Explain how an equilibrium forms from pure reactants. As reactants combine to form products, 1) the concentration of reactants decreases, slowing the rate of the forward reaction, 2) the concentration of products increases, speeding the rate of the reverse reaction. Eventually both rates will be equal. Graph the formation of a dynamic equilibrium from pure reactants. Label the axes. Indicate with an arrow where equilibrium begins. Concentration Time Concentration Time Reactants Or Products Is the increase in product

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
