Calculate heat relesed (in Kj) when 2 moles of gaseous methane undergoes combustion in a rigid vessel of volume 50 liters causing a change in pressure from 10 bar to 2 bar at 300K.  [Useful data : `DeltaH_(f)H_(2)O` =-280kJ/mole,   `DeltaH_(f)CO_(2)`=-390kJ/mole,   `DeltaH_(f)CH_(4)`=-390kJ/mole,=-70kJ/mole],
