Chemistry

Chapter 3, problem 21. An electrochemical battery is used toprovide 1 milliwatt (mW) of power for a (small) light.

The chemical reaction in the battery is: 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,1 bar. 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
