Langmuir hinshelwood kinetics the gas phase reaction c_2h_4 + h2 rightarrow c_2h_6 is conducted over a ni catalyst. the mechanism for the reaction is proposed be the following, where s represents a surface site. c_2h_4 + s c_2h_4 s h_2 + 2s 2h. s c_2 h_4. s + 2h. s c_2 h_6 + 3s reaction 3 is proposed to be rate-limiting (but reversible), with steps 1 and 2 being equilibrated. a. determine the langmuir hinshelwood expression for the rate of formation of ethane in terms of partial pressures of the reactants and product, the equilibrium constants for the three reactions, k_1, k_2, k_3, the total concentration of surface sites, c_t, and the forward rate constant for the surface reaction, k_3. b. the molar rate of ethane production is measured in a differential flow reactor for a series of inlet pressures (in torr) as shown below. it is known that the hydrogen coverage on the surface is very low at these conditions. if this is the case, are the data consistent with the model? explain

12 is it do you think so

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
