Exercise 14.70: Problems by Topic – Le Chatelier's Principle

Coal can be used to generate hydrogen gas (a potential fuel)by the following endothermic reaction.
{rm{C}}left( s right); + ;{rm{H}}_2 {rm{O}}left( g right); rightleftharpoons ;{rm{CO}}left( g right); + ;{rm{H}}_2 left( g right)
If this reaction mixture is at equilibrium, predict whether each ofthe following will result in the formation of additional hydrogengas, the formation of lesshydrogen gas, or have no effect on thequantity of hydrogen gas1)adding more {rm C} to the reaction mixturea),b)the formationof less hydrogen gas,c)noeffect on the quantity of hydrogengas2)adding more {rm{H}}_2 {rm{O}} to the reaction mixturea)the formation ofadditional hydrogen gas,b)the formation of lesshydrogengas,c)3)raising the temperature of the reaction mixturea),b)the formation of lesshydrogen gas,c)no effect on thequantity of hydrogengas4)increasing the volume of the reaction mixturea)the formation ofadditional hydrogen gas,b)the formation of lesshydrogengas,c)

theformation of additional hydrogen gas no effect onthe quantity of hydrogen gas theformation of additional hydrogen gas no effect onthe quantity of hydrogen gas5)adding a catalyst to the reaction mixturea)the formation ofadditional hydrogen gas,b)the formation of lesshydrogengas,c)

no effect onthe quantity of hydrogen gas
