Chem 521 Winter 2019 Assignment 5 due Mar 14, 2019. Oxidizing power of the atmosphere.Remember to show your work whenever possible.Student i.d. ______________5.1.Consider the mechanism for oxidation of CH4 to CO2:CH4 + OH (+ O2)  CH3O2 + H2O(1) CH3O2 + HO2 CH3OOH + O2(2a)CH3O2 + NO (+ O2)  CH2O + NO2 + HO2(2b)CH3OOH + hν (+ O2)  CH2O + HO2 + OH(3a)CH3OOH +OH  CH2O + H2O + OH(3b)CH3OOH + OH CH3O2 + H2O (3c)CH2O + hν (+ 2O2)  CO + 2HO2(4a)CH2O + hν  CO + 2H2(4b)CH2O + OH (+ O2)  CO + HO2 + H2O (4c)CO + OH (+ O2)  CO2 + HO2(5)Hint: This question is based on question 11.3 in Jacob.Assume the following branching ratios:2:1 for loss of CH3O2 by (2a):(2b)1:1:1 for loss of CH3OOH by (3a):(3b):(3c)2:1:1 for loss of CH2O by (4a):(4b):(4c)(a) Show that 9/7 = 1.29 molecules of CH3O2 are produced in the oxidation of 1 molecule of CH4 to CO2

nine moles of Co and 15 moles of Cl2 are placed into a 3 litter reaction chamber at a certain temperature. when equilibrium is reached accprding to Co + Cl2

at a different temperature 10 moles of SO3 are placed into a one litter reaction vessel. find Kc for the same equilibrium equation of SO3 remain at equilibrium
