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:

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

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

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

Which of the following is(are) used in the overall reactions for photosynthesis?

Nimfa-mama [501]

Answer:

Photosynthesis takes the energy of sunlight and combines water and carbon dioxide to produce sugar and oxygen as a waste product. The reactions of respiration take sugar and consume oxygen to break it down into carbon dioxide and water, releasing energy.
