question 80

Multiple Choice

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) ?

• A) Its activation energy is lower than that of 2 H₂(g) + O₂(g ) → 2 H₂O(g).
• B) Its activation energy is the same as that of 2 H₂(g) + O₂(g ) → 2 H₂O(g).
• C) Its activation energy is higher than that of 2 H₂(g) + O₂(g ) → 2 H₂O(g).
• D) There is no relationship between its activation energy and that of 2 H₂(g) + O₂(g ) → 2 H₂O(g).
