The value of the equilibrium constant for the reaction of nickel(II) ions with cadmium metal is 1.17 * 10⁵. Calculate $\Delta$G$\degree$or the reaction at 25$\degree$C.

Question

Quizplus · Accepted Answer

The relationship between the equilibrium constant (K) and the standard Gibbs free energy change ($\Delta$G$\degree$) is given by the equation $\Delta$G$\degree$ = -RT ln(K). At 25°C (298 K), R = 8.314 J/mol·K. Plugging in the values: $\Delta$G$\degree$ = - (8.314 J/mol·K)(298 K) ln(1.17 * 10^5) = -28.9 kJ.
