Question 32

Carbon monoxide and oxygen react together in a catalytic converter. Carbon dioxide is produced.

What is the balanced equation for this reaction?

A

CO+O→CO2\text{CO} + \text{O} \rightarrow \text{CO}_2CO+O→CO2​

B

2CO+O2→2CO22\text{CO} + \text{O}_2 \rightarrow 2\text{CO}_22CO+O2​→2CO2​

C

CO+O2→CO3\text{CO} + \text{O}_2 \rightarrow \text{CO}_3CO+O2​→CO3​

D

CO+O2→CO2\text{CO} + \text{O}_2 \rightarrow \text{CO}_2CO+O2​→CO2​
