Given that the reaction 2 H2(g) + O2(g) → 2 H2O(g) is exothermic, which of the following is true of the reaction 2 H2O(g) → 2 H2(g) + O2(g) ?
Its activation energy is lower than that of 2 H2(g) + O2(g) → 2 H2O(g).
+
Its activation energy is the same as that of 2 H2(g) + O2(g) → 2 H2O(g).
Its activation energy is higher than that of 2 H2(g) + O2(g) → 2 H2O(g).
There is no relationship between its activation energy and that of 2 H2(g) + O2(g) → 2 H2O(g).
