If we imagine that oxygen (O2) and hydrogen (H2) are both ideal gases, what measurable properties will be identical if 1 mole of each element is kept under the same pressure? What
measurable property will be different?

Please have a specific answer, thanks

Hi myself Shrushtee.

Explanation:

Activation energy = It is defined as the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.

The activation energy for the water formation reaction is very high at room temperature due to this reaction does not take place, So the correct option is [A]
