Question

${\text{CO}}_2\text{(g)}+{\text{H}}_2\text{(g)}\to \text{CO(g)}+{\text{H}}_2\text{O(l)}$

The given reaction is an example of:

• A. combination reaction
• B. precipitation reaction
• C. decomposition reaction
• D. redox reaction

Answer 1

The correct option is D redox reaction

• In the given reaction, oxidation and reduction is occuring simultaneously as carbon dioxide is reduced to carbon monoxide by losing oxygen and hydrogen is oxidised to water by gaining oxygen.
• The reaction in which oxidation and reduction occurs simultaneously is called a redox reaction.
