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

1.) Why does the heart rate speed up during exercise?

Yakvenalex [24]

1.) When a man is engaged to continuous exercise or work, not only his muscles are working but also there is increase in the rate of respiration too. This accelerated rate of respiration and heartbeat provides more oxygen and food to the body. So all the organs and organ systems work in coordination. 2.) I'm sorry that I don't know the answer to your question. The one which I know, I have already written.
