Determine δg when [ni(nh3)62+] = 0.010 m, [ni2+] = 0.0010 m, and [nh3] = 0.0050 m. in which direction will the reaction proceed to achieve equilibrium? ni2+(aq) + 6 nh3(aq) ⇌ ni(nh3)6 2+(aq) is kf = 5.6 × 108 at 25°

Given:

The reaction is

We know that

Δ

Δ

Δ

For the given reaction the reaction quotient will be :

Q = \frac{[Ni(NH_{3} )_{6} ^{+2}] }{[Ni^{+2} ][NH_{3}]^{6}

On putting values

Q  will be equal to =

The relation between standard and other free energy change is

ΔG = Δ

Thus

ΔG = (-49906.8) + (8.314)(298) ( ln ()

ΔG = (-49906.8) + 84466

ΔG = 34535 J / mol K

ΔG  is positive so reaction is not spontaneous in forward direction

It will proceed in reverse direction, it will move from product to reactant

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
