1. For a certain process, at 300.K,G=47.7kJ and H=7.0kJ. If the process is carried out reversibly, determine the amount of useful work that can be performed. 2. Water gas, a commercial fuel, is made by the reaction of hot coke carbon with steam. C(s)+H2O(g)CO(g)+H2(g) When equilibrium is established at 828C the concentrations of CO,H2, and H2O are 4.00102M,4.00102M, and 1.00102M, respectively. Calculate the value of G for this reaction at 828C. 3. For the reaction 2HF(g)H2(g)+F2(g),G=38.3kJ, at 1000K. Calculate K. 4. The equilibrium constant of a certain reaction was measured at various temperatures to give the plot shown below. What is S for the reaction in J/molK ? 5. For the following reaction, CO2(g)+2H2O(g)CH4(g)+2O2(g),H=803kJ. How would you increase K
