Suppose the formation of nitryl fluoride proceeds by the following mechanism: step elementary reaction rate constant (g) (g) (g)
ziro4ka [17]

Complete Question

The complete question is shown on the first uploaded image  

Answer:

a

  2NO_2 _{(g)} +  F_2_{(g)} ---->  2NO_2 F_{(g)}

b

  r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}

Explanation:

      From the question we are told that

          The formation mechanism is  

                      NO_2_{(g)} + F_2 _{(g)} ----> NO_2 F_{(g)} + F_{(g)}

                      F_{(g)} +  NO_2 _{(g)} ---> NO_2 F_{(g)}

The overall balanced equation is

              2NO_2 _{(g)} +  F_2_{(g)} ---->  2NO_2 F_{(g)}

We combined the first reactant and the last product and the balanced the number of mole

     The observable rate law is

                 r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}

This rate law is derived from the balanced chemical equation

How do you find the theoretical yleld of a chemical reaction?
kvv77 [185]

Answer:

Explanation:

To calculate the theoretical yield, determine the number of moles of each reactant, in this case the sole reactant ethanol. Convert the 100 g to moles; the molecular weight of ethanol is 46 g/mole, therefore: Since there is only one reactant, it is also the limiting reagent.
