Methane and Oxygen exist in a stoichiometric mixture at 500 kPa and 298K. They are ignited and react at constant volume. Combustion is complete. Imagine two scenarios, one where this reaction occurs in an insulated container, one where it reacts at constant pressure. The two products from these two scenarios undergo adiabatic expansion in a piston cylinder device. Find the total work done for both processes and draw a P-v and T-s Diagram for each.
