Chapter 3: Problem 65

Consider the combustion of carbon monoxide (CO) in oxygen gas $$ 2 \mathrm{CO}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{CO}_{2}(g) $$ Starting with 3.60 moles of \(\mathrm{CO},\) calculate the number of moles of \(\mathrm{CO}_{2}\) produced if there is enough oxygen gas to react with all of the CO.

Short Answer

Expert verified
If 3.60 moles of carbon monoxide reacts with sufficient oxygen, it will produce 3.60 moles of carbon dioxide.

Step by step solution

01

Identify the stoichiometric ratio

From the balanced equation, it can be seen that 2 moles of CO combine with 1 mole of O2 to give 2 moles of CO2. Therefore, the stoichiometric ratio between CO and CO2 is 1:1. This means for every 1 mole of CO that reacts, 1 mole of CO2 is produced.
02

Apply the ratio to find the quantity of CO2

Since the ratio between CO and CO2 is 1:1, the amount of CO2 produced will be equivalent to the amount of CO reacted. Given that 3.60 moles of CO is available and will react completely, then 3.60 moles of CO2 will be produced.
