Unit 6.1: Endothermic and Exothermic Processes

Determine if a process is endothermic or exothermic and assign the proper sign to ∆H.

1. Is melting ice endothermic or exothermic? Explain your reasoning.
2. A + B → AB ΔH = −50 kJ·mol_rxn⁻¹
   Is the reaction above endothermic or exothermic. Justify how you know.
