In the following reaction, what stresses (changes) could we apply to the reaction in order to increase the production of H2O (g)? (hint: there are 4 correct choices) CO2 (g) + H2 (g) + heat ⇌ CO (g) + H2O (g)

CO (g) is added
CO (g) is removed
H2 (g) is added
H2 (g) is removed
CO2 (g) is added
CO2 (g) is removed
System (reaction) is heated
System (reaction) is cooled
Pressure is increased
Pressure is decreased
