Problem 14.28 Consider a hypothetical reaction between A, B, and C that is first order in A, zero order in B, and second order in C.

(a) Write the rate law for the reaction.

(b) How does the rate change when [A] is doubled and the other reactant concentrations are held constant?

(c) How does the rate change when [B] is tripled and the other reactant concentrations are held constant?

(d) How does the rate change when [C] is tripled and the other reactant concentrations are held constant?

(e) By what factor does the rate change when the concentrations of all three reactants are tripled?

(f) By what factor does the rate change when the concentrations of all three reactants are cut in half?

Step-by-Step Solution:

Step 1 of 5) Equations 18.3 and 18.4 both depend on molecular collisions. (Section 14.5) The concentration of molecules is greater at low altitudes, and so the rates of both reactions are greater at lower altitudes. Because these two effects vary with altitude in opposite directions, the highest rate of O3 formation occurs in a band at an altitude of about 50 km, near the stratopause (Figure 18.1). Overall, roughly 90% of Earth’s ozone is found in the stratosphere. The photodissociation of ozone reverses the reaction that forms it. We thus have a cycle of ozone formation and decomposition, summarized on the next page:Variation in ozone concentration in the atmosphere as a function of altitude.
