1.What is the maximum amount of useful work that could theoretically be obtained at 25 degrees celsius and 1 bar from the combustion of 48g of natural gas,CH4(g), to give CO2(g) and H2O(g)?

2.The equilibrium below is established when a gaseous mixture of 0.05 mol of hydrogen and 0.05 mol of iodine are placed in a closed system of volume 500ml. Given the equilibrium constant,Kc=49.5, at the experimental temperature, calculate the equilibrium concentrations of H2(g),I2(g), and HI(g).

H2(g)+I2(g) === 2HI(g)
