Chapter 5, Problem 7P(choose chapter or problem)
When ethene is mixed with hydrogen in the presence of a platinum catalyst, hydrogen adds across the double bond to form ethane. At room temperature, the reaction goes to completion. Predict the signs of \(\Delta H^{\circ} \text { and } \Delta S^{\circ}\) for this reaction. Explain these signs in terms of bonding and freedom of motion.
