An electrochemical battery is used to provide 1 milliwatt (mW)of power for a (small) light. The chemical reaction in the batteryis: 1/2 N2 (g) + 3/2 H2 (g) → NH3 (g)
a. What is the free-energy change for the reaction at 25o C, 1bar?
b. Calculate the free-energy change for the reaction at 50o C, 1bar. State any assumptions made for this calculation.
c. The limiting reactant in the battery is 100 g of H2.Calculate the maximum length of time (seconds) the light canoperate at 25o C
