Question
Transcribed Image Text:For the reaction
2SO₂(g) + O₂(g) 2SO3(g)
AGº = -143.5 kJ and AS° = -187.9 J/K at 289 K and 1
atm.
The maximum amount of work that could be done by this
reaction when 2.41 moles of SO₂(g) react at standard
conditions at this temperature is
kJ.
Transcribed Image Text:Consider the reaction
CaCO3(s)- →CaO(s) + CO₂(g)
The standard free energy change for this reaction is 130.4
kJ. The free energy change when 1.87 moles of CaCO3(s)
react at standard condition is 243.8 kJ.
What is the maximum amount of useful work that the
reaction of 1.87 moles of CaCO3(s) is capable of producing
in surroundings under standard con ions? If no work
can be done, enter none.
kJ
