Question

I need help solving the following Physical chemistry kinetics problem using Wolfram Mathematica please. Please see the attached documents.

I would really appreciate your help.

Problem 1. Assume that the reaction
Оз + М >
02 + M
2
is elementary and write down a plausible rate equation for dO3 (t)/dt. O3(t) is the
concentration of ozone (mol/liter) at time t.
Problem 2. Assume that you know that the reaction takes place in two steps
03 + M 2 02 +0+ M
(1)
and
0+ 03 → 2 02
(2)
Here M is an inert molecule, such as nitrogen or argon. Write rate equations for
all compounds in reaction; express dO3/dt, dO/dt and dO2/dt, in terms of the
concentrations of O2, 03, 0, and M.
Problem 3. Write the rate equations for the reactions 1 and 2 (given in problem
2) in terms of the extents of reactions.

Problem 4. Derive an equation for
dO3(t)/dt by using the steady state approximation.
Problem 5. The rate constants for these reactions have been measured and
they are
k = 2.2 1012 exp[- 2400(cal/mol)/RT]
k-1 = 2.96 10' exp[890(cal/mol)/RT]
k2 = 3.37 1010 exp[-5700(cal/mol)/RT]
One activation energy is negative. Is that sensible? What does that suggest? If
these numbers are correct is the steady state approximation correct if the
temperature is 500 K ?
