Question

why hydrogen is less reactive at room temperature

Answer 1

Hydrogen gas has the molecular formula H2. At room temperature and under standard pressure conditions, hydrogen is a gas that is tasteless, odorless and colorless. Hydrogen can exist as a liquid under high pressure and an extremely low temperature of 20.28 kelvin(−252.87°C, −423.17 °F).

Answer 2

Answer:

Hydrogen is less reactive in room temperature because the bond in H-H molecules is very strong with bond dissociation energy of 435.9 kJ (mol)^-1. For this reason many catalysts are used in reaction involving H2. The catalyst first weakens or break the H-H bond and then the reaction goes on. However at higher temperatures the bond weakens and thus H2 reacts easily.
