Predict the signs (-, +, or 0) of $\Delta$H and $\Delta$S, in that order, for the reaction: O₂(g) $\rarr$ 2O(g). A) +,- B) -, + C) +, + D) -, - E) None of the above

Question

Quizplus · Accepted Answer

The reaction involves breaking the O=O double bond in O2 to form two separate O atoms, which requires energy, making $\Delta$H positive. The reaction increases disorder as one molecule of O2 gas becomes two separate O atoms, making $\Delta$S positive.
