Question 8

The reaction between carbon monoxide, CO\text{CO}CO, and steam, H2O\text{H}_2\text{O}H2​O, is reversible:

CO(g)+H2O(g)⇌CO2(g)+H2(g) \text{CO(g)} + \text{H}_2\text{O(g)} \rightleftharpoons \text{CO}_2\text{(g)} + \text{H}_2\text{(g)} CO(g)+H2​O(g)⇌CO2​(g)+H2​(g)

The forward reaction is exothermic. What will increase the yield of hydrogen, H2\text{H}_2H2​?

A

Adding a catalyst

B

Decreasing the concentration of carbon monoxide

C

Decreasing the temperature

D

Decreasing the pressure
