Ag can be eroded by gaseous H2S via reaction: H2S(g) + 2Ag(s) → Ag2S(s) + H2(g). Under ambient condition (i.e. 298 K, 1 atm), AfGº of Ag2S(s) and H2S(g) are -40.26 kJ.mol-? and -33.02 kJ.mol“!, respectively. Please answer: (a) Whether Ag will be eroded to form Ag2S(s) when it is exposed to a mixture of H2S(g) and H2(g) with Vhys : VH2 = 1:1 under ambient condition. (b) What is the maximum mole fraction of H2S(g) in the H2(g)/H2S(g) mixture...

1.Calculate the free energy(ΔG°)of the following reactions: a)H2(g) + O2(g)→ H2O2(g) b)H2O2(g) + H2(g) → 2 H2O (g) How do the free energy values for these two reactions compare to the free energy of the combustion of hydrogen gas? Hint: (ΔG) is a state function, therefore Hess’s law is applicable.The combustion of hydrogen gas is modeled by the overall equation is 2 H2(g) + O2(g)→ 2 H2O(g). 2.Based on your calculations in the previous question and your understanding of reaction...
