Argon $($Ar$),$ at $250$ K$,1$ bar with a mass ow rate of $3$ kg$/$s enters the insulated mixing chamber shown in the gure below and mixes with carbon dioxide $($CO $)$ entering as a separate stream at $575$ K$,1$ bar with a mass ow rate of $0\mathrm{.}5$ kg$/$s$.$ The mixture exits at $1$ bar. Assume ideal gas behavior with k $=1\mathrm{.}67$ for Ar and k $=1\mathrm{.}25$ for CO $.$ For steady$-$state operation, determine: $($a$)$ the molar analysis of the exiting mixture. $($b$)$ the temperature of the exiting mixture, in K$.($c$)$ the rate of entropy production, in kW$/$K$.1=1=22$
