A rigid container is charged with butane, C4H8, and air in a stoichiometric ratio at P0, T0.

Question:

A rigid container is charged with butane, C4H8, and air in a stoichiometric ratio at P0, T0. The charge burns in a short time with no heat transfer to state 2. The products then cool with time to 1200 K, state 3. Find the final pressure, P3, the total heat transfer, 1Q3, and the temperature immediately after combustion, T2.
