Question

A researcher places a reactant for decomposition in an expandable reaction chamber and purges the air from the vessel with nitrogen gas. The 500mL reaction vessel is sealed at a pressure of 1.00atm and 390K. If the decomposition reaction was triggered by an electrical shock, producing 3.1g of oxygen gas, what would the volume (L) of the reaction vessel be if the temperature and pressure were kept constant?

Assume the volume of the reactant took up negligible space.

Answer 1

Final volume of reaction vessel Initial volume of reaction vessel volume of oxygen gas.

Initial volume of reaction vessel is 500 mL.

Volume of oxygen gas

Convert unit from L to mL

Final volume of reaction vessel Initial volume of reaction vessel volume of oxygen gas.

Final volume of reaction vessel
