Question

For the reaction

a.) 2HBr(g) + Cl₂(g)--->2HCl(g) + Br₂(g)

ΔH° = -81.1 kJ and ΔS° = -1.2 J/K

The maximum amount of work that could be done when 2.48 moles of HBr(g) react at 278 K, 1 atm is kJ.

Assume that ΔH° and ΔS° are independent of temperature.

b.) CaCO₃(s)--->CaO(s) + CO₂(g)

The standard free energy change for this reaction is 130.4 kJ. The free energy change when 1.92 moles of CaCO₃(s) react at standard condition is

kJ.

What is the maximum amount of useful work that the reaction of 1.92 moles of CaCO₃(s) is capable of producing in the surroundings under standard conditions? If no work can be done, enter none.
kJ
