Chapter 23, Problem 23.34P
Interpretation Introduction

Interpretation:

Value of ΔGrxno at 25°C has to be calculated. The direction in which the reaction is spontaneous under standard conditions has to be identified. Also, the value of value of ΔGrxn when [Co3+]=0.0050 M, [NH3]=0.10 M and [Co(NH3)6]3+=1.00 M has to be calculated and direction in which the reaction is spontaneous under standard conditions has to be identified.

Concept Introduction:

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by ΔG. Value of ΔGrxno is determined as follows,

  ΔGrxno=RTln K

Under standard conditions, the reaction is spontaneous when ΔGrxno is negative whereas the reaction is not spontaneous when ΔGrxno is positive.

The formula of ΔGrxn in is given below,

    ΔGrxn=RTln (QcKc)

If ΔGrxn<0 then the reaction is spontanous in forward reaction and so the reaction will favor products.

If ΔGrxn>0 then the reaction is spontanous in backward reaction and so the reaction will favor reactants.

If ΔGrxn=0 then the reaction is at equilibrium.
