Astoichiometric methane (gas) air mixture at 298k is combusted in an adiabatic sssf reactor. calculate the meat or reaction per kmol methane if the products leave the reactor at 1200k. account for variation in specific heats.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
