Whitepunk [10]3 years ago
7 0

Answer:

Judging from the wording of he question, you mean units. If that is indeed the case, the answer is g/Mol (grams per mol)

Let me know if my interpretation is incorrect and please tell me what you are actually trying to find.

Ni2+(aq) + 6 NH3(aq) ⇌ Ni(NH3)6 2+(aq)
Jet001 [13]

Answer:

a) ΔGº= -49,9 KJ/mol = - 50 KJ/mol

b) The reaction  goes to the right to formation of products

c) ΔG= 84,42 KJ/mol. The direction is to reactive, to the left

Explanation:

a) ΔGº= - RTLnKf

You need to convert Cº to K. 25ºC=298K

Then, ΔGº= - 3,814 J/molK * 298K* Ln(5.6 *10^8)= - 49906 J/mol = -49,9 KJ/mol = - 50 KJ/mol

b) The ΔGº < 0, that means the direct reaction is spontaneous when te reactive and products are in standard state. In other words the reaction goes to the right, to formation of products

c) The general ecuation for chemical reaction is aA + bB → cD + dD. Thus

ΔG=ΔGº + RTLn (([C]^c*[D]^d)/[A]^a*[B]^b)

In this case,

ΔG=ΔGº + RTLn ([Ni(NH3)62+] / [Ni2+]*[NH3]^6 )= 84417 J/mol =84,42 KJ/mol

ΔG >0 means the reaction isn't spontaneous in the direction of the products. Therefore the direction is to reactive, to the left

A mixture of helium, nitrogen and oxygen has a total pressure of 756 mmHg. The partial
Karolina [17]

Answer:

The  partial pressure of oxygen in the mixture is 296 mmHg.

Explanation:

The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone.

This relationship is due to the assumption that there are no attractive forces between the gases.

So, in this case, the total pressure is:

PT=Phelium + Pnitrogen + Poxygen

You know:

  • PT= 756 mmHg
  • Phelium= 122 mmHg
  • Pnitrogen= 338 mmHg
  • Poxygen= ?

Replacing:

756 mmHg= 122 mmHg + 338 mmHg + Poxygen

Solving:

756 mmHg - 122 mmHg - 338 mmHg = Poxygen

Poxygen= 296 mmHg

<u><em>The  partial pressure of oxygen in the mixture is 296 mmHg.</em></u>
