What is the reaction that occurs when a closed, evacuated reaction vessel at some temperature is charged with 2.00 atm of [tex]H_2[/tex] gas and 2.00 atm of [tex]O_2[/tex] gas?

Answer :

Final answer:

When 2.00 atm of H2 gas and 2.00 atm of O2 gas react in a closed vessel, they form 2.00 atm of H2O gas, releasing heat in the process.

~~

Explanation:

The question is about a chemical reaction that occurs when a vessel is charged with 2.00 atm of H2 gas and 2.00 atm of O2 gas. These gases will react to form water in accordance with the chemical equation: 2H2(g) + O2(g) -> 2H2O(g)

This specific reaction is an exothermic process, which means heat is released. When 2 molecules of hydrogen gas react with 1 molecule of oxygen gas, 2 molecules of water are formed, and 286 kJ of heat are released to the surroundings. These molecules react in a strict 2:1 ratio.

In the case of having the gases at 2 atm each, the gases will react until one of the reactants is completely consumed, which will in this case form 2 atm of water vapor, as this reaction goes nearly to completion under these conditions.
