We are given the reaction: 2CO + O2 → 2CO2.
• In order to determine how many moles of CO2 could be produced from 0.05 moles of CO( Carbon monoxide)
• We need to determine the mole ratio first :
2CO + O2 → 2CO2
2 : 1 : 2
0.05moles : 0.025 : 0.05
• We can see that, 0.05 moles of CO will produce 0.05 mole of CO2 , their mole ratio is 2:2 which is the same as 1: 1, they are equal.
Therefore , 0.05moles of CO2 will be produced. option b is correct.
