For a particular reaction, Δ H ∘ = 55.4 kJ ΔH∘=55.4 kJ and Δ S ∘ = 94.1 J/K. ΔS∘=94.1 J/K. Assuming these values change very lit

Answer:

The temperature at which the reaction changes from non-spontaneous to spontaneous is 588.735 K

Explanation:

The spontaneity of a reaction is determined by the change in Gibbs Free Energy, $\Delta G^{0}$ .

$\Delta G^{0} =\Delta H^{0} -T\Delta S^{0}$

If $\Delta G^{0}$ is greater than zero, then a reaction is feasible.

If $\Delta G^{0}$ is less than zero, then a reaction is not feasible.

To determine the temperature at which the reaction changes from non-spontaneous to spontaneous, we should equate the $\Delta G^{0}$ to zero.

We take $\Delta G^{0}=0$ as the limiting condition.

$T=\frac{\Delta H^{0}}{\Delta S^{0}}=\frac{55.4\times10^{3}}{94.1}=588.735K$

Therefore, the temperature is: 588.735K
