1). For a reversible reaction at equilibrium:
A?B
i) What is the relationship between the rate law of the forward reaction, the rate law of the reverse reaction, and the equilibrium expression?
ii). If KC is much greater than 1, what are the relative values of kf and kr? 2). Considering a reversible reaction:
A?B
in which the initial [A] is 1.00 M, and the initial [B] is 0.00 M.
i). Draw a graph that depicts [A] vs time, and [B] vs time on the same set of axes.
ii). If the forward reaction is first order, sketch a graph that depicts the rate of disappearance of A and the appearance of B over time. At equilibrium, do the forward and reverse reactions essentially stop occurring?
3). We always start a discussion of an equilibrium reaction with a reaction equation. If equilibrium can be reached by initially starting with only reactants or with only the products, does it matter how we write the equilibrium expression? Why?
4). Explain LeChatelier's Principle. What factors must be considered in determining the equilibrium position (i.e. favoring reactants or products) of an equilibrium reaction? Illustrate an example for each.
