The reaction is 2H2 + O2>>>2H2O
you have in the reactants, a partial pressure of O2 of 200kPa, and of the H2 a partial pressure of 200kPa. So you have excess O2.
You will get then a partial pressure from the reaction leaving half the initial O2, and replacing the H2 used with H2O.
final pressure O2: 100kPa
final pressure H2: 0 kPa
final pressure H2O:200kPa
total pressure: 300kpa
(assuming same temp)
Could you show me where to start on solving this equation?
The reaction in question will be carried out in a calorimeter. The volume of the chamber inside is 2.00 L. Experiment starts by evacuating the chamber to 0.00 kPa. Then oxygen gas is filled into the chamber till pressure 200. kPa. Then hydrogen gas is filled into the same chamber until total pressure 400. kPa. The oxygen and hydrogen mixture is ignited by a spark with 3.00 kJ energy. Calculate the total pressure inside the chamber after reaction.
