The reaction is           2 NO (g) <----> N2(g) + O2

partial pressures

Initial                                 37.30          0          0

Change                            -2p                +p        +p

Equilibrium                          37.30-p        p          p

Kp = pN2 X pO2 / (pNO)^2

2400 = p^2 /  (37.30-p)^2

3339096 - 179040p + 2400p^2 = p^2

2399p^2 + 3339096  -179040 p = 0

On solving

p = 36.55atm

Thus partial pressure of N2 and O2 = 36. 55 atm

How many different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine at
svp [43]
Answer:
             THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.

Explanation:
                   When two Hydrogen atoms in ethylene (C</span>₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is C₂H₂FCl.
                    Compounds having same Molecular formula but different structural formula are called as Isomers.
                     First Isomer of C₂H₂FCl is 1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
                     Other two Isomers are Geometrical Isomers of 1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms (<em>trans</em>)-1-chloro-2-fluoroethene and the one in which both are in same side is called as (<em>cis</em>)-1-chloro-2-fluoroethene.

Based on the balanced equation 2C2H2 + 5O2 → 4CO2 + 2H2O calculate the number of excess reagent units remaining when 52 C2H2 mol
erica [24]

Answer:

20 molecules of oxygen gas remains after the reaction.

Explanation:

2C_2H_2 + 5O_2\rightarrow 4CO_2 + 2H_2O

Molecules of ethyne = 52

Molecules of oxygen gas = 150

According to reaction, 2 molecules of ethyne reacts with 5 molecules of oxygen gas.

Then 52 molecules of ethyne will react with:

\frac{5}{2}\times 52=130 molecules of oxygen gas.

As we can see that we have 150 molecules of oxygen gas, but 52 molecules of ethyne will react with 130 molecules of oxygen gas. So, this means that ethyne is a limiting reagent and oxygen gas is an excessive reagent.

Remaining molecules of recessive reagent = 150 - 130 = 20

20 molecules of oxygen gas remains after the reaction.
