Which outcome results when using a metal hydride to store hydrogen fuel in a vehicle during refueling?

💡 Explanation

When hydrogen is absorbed into a metal hydride, an exothermic reaction occurs because chemical bonds form between hydrogen atoms and the metal lattice, releasing heat into surroundings. Therefore exothermic heat release predominates, rather than cooling, expansion, or catalyst degradation which depend largely on discharging or catalyst properties.
