Volume-volume problems example 1 what volume of O2 reacts CO to produce 0.5mole of Co2 at STP?
The balanced chemical equation for the reaction of CO and O2 to produce CO2 is:
CO + O2 -> CO2
According to the stoichiometry of this equation, it takes 1 mole of O2 to react with 1 mole of CO to produce 1 mole of CO2. Therefore, to produce 0.5 moles of CO2, we need 0.5 moles of CO and 0.5 moles of O2.
At STP (Standard Temperature and Pressure), the volume of 1 mole of any gas is 22.4 L. Therefore, the volume of 0.5 moles of O2 is:
0.5 moles O2 x 22.4 L/mole = 11.2 L
So, 11.2 L of O2 reacts with 0.5 moles of CO to produce 0.5 moles of CO2 at STP.
