For the decomposition of hydrogen peroxide to water and oxygen, H2O2(g) → H2O(g) + O2(g)
ΔH° = −106 kJ,and ΔS° = +0.0580 kJ/K.Under which of the following conditions is the reaction spontaneous (ΔG° < 0) ?
A) The temperature must be greater than 1.83 × 103 K.
B) The temperature must be less than 1.83 × 103 K.
C) The temperature must be between 225 K and 1.83 × 103 K.
D) ΔG° is always less than zero.
