Forms of K: Multiplying reactions by an integerV. Finding K for an overall reactionVI. Manipulating equilibrium constant expressionsCurrent LectureI. Forms of K: Multiplying reactions by an integera. If the coefficients of a balanced equation are multiplied by a common factori. For n(aA+bBcC+dD)ii.K1=Kn=([C]c[D]d[A]a[B]b)nII. Finding K for an overall reactiona. Show that the overall Kc for the reaction sequence is the same as the product of the Kc’s of the individual reactionsb. Given that both reactions occur at the same temperature, find Kc for the overall reactionIII. Manipulating equilibrium constant expressionsa. The form of K depends on the direction in which the balanced equation is writtenb.Kc(rev)=1Kc(fwd)c. For an overall reaction that is the products of two or more individual reactionsThese notes represent a detailed interpretation of the professor’s lecture.
