Consider the diagram that follows, which represents two steps in an overall reaction. The red spheres are oxygen, the blue ones are nitrogen, and the green ones are fluorine. d. Write the rate law for the overall reaction if the first step is the slow, rate-determining step. [Section 14.5]
Based on the following reaction profile, how many intermediates are formed in the reaction A⟶C? How many transition states are there? Which step, A⟶B or B⟶C, is the faster? For the reaction A⟶C, is Δ𝐸 positive, negative, or zero? [Section 14.5]
(b) Name three factors that can affect the rate of a chemical reaction.
b. As the temperature increases, does the reaction rate usually increase or decrease?
(c) As a reaction proceeds, does the instantaneous reaction rate increase or decrease?
Consider the following hypothetical aqueous reaction: A1aq2S B1aq2. A flask is charged with 0.065 mol of A in a total volume of 100.0 mL. The following data are collected: Time (min) 0 10 20 30 40 Moles of A 0.065 0.051 0.042 0.036 0.031 (a) Calculate the number of moles of B at each time in the table, assuming that there are no molecules of B at time zero and that A cleanly converts to B with no intermediates.
