<span>The nucleus is the organelle present in eukaryotic cells with the main function in the control of all cell activities and maintaining the gene integrity. Namely, it contains the genetic material of the cell in the form of chromosomes (DNA molecules in complex with proteins). It is enclosed by the nuclear membrane which regulates the movement of proteins and RNA in and out of the nucleus.</span>

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
