Chemistry

Carbon dioxide dissociates to form carbon monoxide.

a. Write down the balanced stoichiometric equation representingthe complete dissociation of CO2 to CO

b. determine the equilibrium constant for this reaction at 2000K

c. Write down the balanced stoichiometric equation when 25% ofCO2 has disassociated into CO

d. What is the value of the equilibrium constant when thisoccurs i.e., when 25% of CO2 has disassociated into CO at 1bar?

e. At what temperature (approximately) does this occur

f. explain if the complete dissociation of CO2 to CO is anendothermic or exothermic reaction.

g. Finally, determine the enthalpy of this reaction at standardconditions to verify if the complete dissociation of CO2 to CO isendothermic or exothermic
