Which of the following process(es) is/are endothermic? (one or more than one correct)
Options:(select one or more)
Answer:
B, C, D
Solution:
(a) Neutralization of a strong acid by a strong base releases about 57 kJ/mol, exothermic. (b) Breaking the lattice forces of solid CO2 to form gas absorbs heat. (c) CS2(l) has Δf H = +89 kJ/mol, so its formation absorbs heat. (d) Fusion always absorbs heat (about +6 kJ/mol). Endothermic: (b), (c), (d). Ans (b),(c),(d).
