Help me understand plz

0.6 mole of O2, 0.8 mole of CO and 0.5 mole of CO2 are added to a 2-L container. The system is heated and 0.15 mole of CO2 is formed.

Does that mean that on top of the initial 0.5 mole of CO2 an additional 0.15 mole of CO2 is formed or does that mean that in total (at equilibrium) 0.15 mole of CO2 has been formed?

Anyone? thx

That is that the container contains 0.65 mole of CO2 : original 0.5 mole + newly formed 0.15 mole.

I would love to see the formula. I cannot understand why CO2 was added in order to create CO2. If we already have 0.5 mole of the stuff, why do we need to make 0.15 mole of it?

Hello MM

Neither do I know the reason CO2 was added to the container. But one could suppose they put it in order to know the effect of the end product concentration on the reaction CO + 0.5 O2 ? CO2.
