Remarkably, a catalytic system that uses light energy to hydrolyze water into hydrogen H 2 (g) and O(g) has been devised ( Science 334, 2011: 645–648) to capture and efficiently store solar energy. Hydrogen is "clean burning" in that it yields only H 2 O. In this problem you will contrast the combustion of 1 kg H 2 (g) to that of 1 kg of n -octane. a. Calculate the enthalpy, entropy, and free-energy change on burning 1 kg of H2(g) to H2O(l) at 25°C and 1 bar. b. Calculate the enthalpy, entropy, and free-energy change on burning 1 kg of n -octane( g ) to H2O(l) and CO2(g) at 25°C and 1 bar.
