- When nitrogen dioxide reacts with carbon monoxide, the following reaction occurs. Â NO2(g)+CO(g)NO(g)+CO2(g)The following data are obtained at a certain temperature: (a) What is the order of the reaction with respect to NO2, CO, and overall? (b) Write the rate expression of the reaction. (c) Calculate k for the reaction. (d) When [ NO2 ]=0.421Mand [ CO ]=0.816M, what is the rate of the reaction at the temperature of the experiments?The following rate constants were obtained in an experiment in which the decomposition of gaseous N2O; was studied as a function of temperature. The products were NO, and NO,. Temperature (K) 3.5 x 10_i 298 2.2 x 10"4 308 6.8 X IO-4 318 3.1 x 10 1 328 Determine Etfor this reaction in kj/mol.Hello, i need help with these questions. Please provide a handwritten solution for better understanding. One pathway for the destruction of ozone in the upper atmosphere is O3(g) + NO(g)---> NO2(g) + O2(g) Slow NO2(g) + O(g) ---> NO(g) + O2(g) Fast Overall reaction: O3(g) + O(g)---> 2O2(g) Ea is 14.0 kJ/mol, for the uncatalyzed reaction: O3(g) + O(g) --> 2O2(g) 1a) Ea for the same reaction, when catalyzed as above, is 11.9 kJ/mol.At -37°C, what is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed reaction?(Assume the frequency factor A is the same for each reaction.) 1b) One of the concerns about the use of freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the reaction CCl2F2 CF2Cl + Cl (photolysis of Freon-12) Chlorine atoms can also act as a catalyst for the destruction of ozone.The activation energy for the reaction Cl + O3 --> ClO + O2 is 2.1…
- 9 Why did you do initial - final temperature instead of final temp - initial temp?The thermal decomposition of ozone in the gas phase is thought to proceed via the reactive intermediate, oxygen atom; overall: 2 O_3 --> 3 O_2. Mechanism: O_3 --> O_2 + O k_1 O + O_2 --> O_3 k_2 O + O_3 --> 2 O_2 k_3 Apply the steady-state approximation and obtain an expression for the rate of loss of ozone, d[O_3]/dt. You may assume that [O_2] is large and unchanging. (show all work)The age of wine can be determined by measuring the trace amount of radioactive tritium, 3H, present in a sample. Tritium is formed from hydrogen in water vapor in the upper atmosphere by cosmic bombardment, so all naturally ocurring water contains a small amount of this isotope. Once the water is in a bottle of wine, however, the formation of additional tritium from the water is negligible, so the tritium initially present gradually diminishes by a first-order radioactive decay with a half-life of 12.5 years. If a bottle of wine is found to have a tritium concentration that is 0.184 that of freshly bottled wine (i.e. [3H]t = 0.184 [3H]0), what is the age of the wine?

Express your answer in minutes to two significant figures.The radioactive isotope carbon-14 is present in small quantities in all life forms, and it is constantly replenished until the organism dies, after which it decays to stable carbon-12 at a rate proportional to the amount of carbon-14 present, with a half-life of 5550 years. Suppose C(t) is the amount of carbon-14 present at time t. (a) Find the value of the constant k in the differential equation C′=−kC. k= ?
