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

Formic acid, hcooh, is a weak electrolyte. what solutes are present in an aqueous solution of this compound? write the chemical
ioda
<span>All acids form their conjugate base and a proton or H+ in an aqueous solution, in water. Since formic acid is an acid, although a weak electrolyte, it will react with water to form the conjugate base HCOO with a negative 1 charge. The other solute will be the proton H+, also written as hydronium H3O+.</span>

Concentration Calculation: Using your Trial 1 ‘difference in final volumes’ data from procedure II and procedure III, and the kn
Digiron [165]

Subtract the mass of the solute from the whole solution volume.

Molarity, percent by mass, and percent by volume are all ways to represent concentration.

By dividing the number of moles by the number of liters of water utilized in the solution, we can compute the molar concentration. Here, for instance, 1.25 L of water has entirely dissolved the acetic acid. In order to determine the molar concentration, which is 0.1332 M, divide 0.1665 moles by 1.25 L. A titration is a method for figuring out the concentration of an unknown solution by using a solution with known concentration.

Finding the concentration for each sample's absorbance on the standard curve is the first step in calculating the sample concentration based on the standard curve. The next step is to multiply the concentration by the dilution factor for each sample.
