9 THE REACTION QUOTIENT AND LECHATELIER’S PRINCIPLE We have seen that the equilibrium constant is an important quantity. It turns out that one can extend the de fi nition of the equilib- rium constant to non-equilibrium situations. The Reaction Quotient Under non-equilibrium situations the ratio of the concentra- tion (or partial pressures) of products to reactants is called the reaction quotient, Q = [ products ] [ reactants ] . (9.1) So, for the reaction, aA + bB ­ cC + dD, (9.2) the reaction quotient is

Unformatted text preview: Q = [ C ] c [ D ] d [ A ] a [ B ] b . (9.3) The reaction quotient applies to the current situation of the reaction and thus changes over the course of the reaction. Clearly, at equilibrium Q = K. Beyond that, however, if Q < K the reaction will proceed in the forward direction (make more products). And, if Q > K the reaction will proceed in the reverse direction (make more reactants). THE REACTION QUOTIENT AND LECHATELIER’S PRINCIPLE 37...

    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.

    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.
