Question

(i) Explain why H2 and O2 do not react at room temperature.

Answer 1

Hydrogen molecules violently reactwith oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. ... But hydrogen does not react with oxygen at room temperature, a source of energy is needed to ignite the mixture.

Answer 2

Answer:

H2 & O2 gases mix at room tempt. with no chemical rxn. This is bcoz the speed of the molecules doesn't provide enough kinetic energy to activate the rxn during collisions between the reactants.
