Problem

Reaction 1:

X \to Y

\Delta G^\circ = +35.0\,\text{kJ}\cdot\text{mol}^{-1}

Reaction 2:

Z \to X

\Delta G^\circ = -50.0\,\text{kJ}\cdot\text{mol}^{-1}

Calculate the standard Gibbs free energy change,

\Delta G^\circ

, for the net reaction

Z \to Y

and state whether the overall process is spontaneous under standard conditions.
