Question

4. A closed 1.0L vessel with diathermal walls has hydrogen (H2) and oxygen (O2) gas at a total pressure of 2.0bar and partial pressures of each of 50%. The vessel is initially at 25.0ºC and maintained in a 25.0ºC environment. The mixture is slowly combusted isothermally. (Assume ideal gas behavior)

a. (20 pts) What will be the final pressure of the mixture?

b. (20 pts) What are the partial pressures of each component gas after the reaction? c. (10 pts) This reaction is used to propel rockets into space. Why would the above results work (or not work) for this purpose?
