Nitrogen dioxide is one of the many oxides of nitrogen (often form another form of NOx, dinitrogen tetroxide A chemical engineer studying this reaction fils a 500. mL flask at 7.9 °C with 4.9 atm of nitrogen dioxide gas. He thèn raises the temperature considerably and when the mixture has come to equilibrium determines that it contains 2.7 atm of nitrogen dioxide gas The engineer then adds another 1.2 atm of nitrogen dioxide, and allows the mixture to come to equilibrium again.

1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.

Explanation:

initially

4.9 atm        0  

At equilbrium:

(4.9-2p)        p

Pressure of nitrogen dioxide gas at equilibrium = 2.7 atm

So, (4.9-2p) = 2.7 atm

p = 1.1 atm

The value of equilibrium constant :

After addition of 1.2 atm of nitrogen dioxide gas more to the flask,will the reestablish an equilibrium in flask.

(2.7+1.2) atm                 1.1 atm

At second equilibrium

(2.7+1.2-2x) atm                 (1.1+x) atm

The expression of :

Solving for x:

x = 0.3827 atm

The pressure of dinitrogen tetroxide after equilibrium is reached the second time:

(1.1+x) atm = (1.1+0.3827) atm =1.4827 atm ≈ 1.5 atm

1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
