A gaseous mixture of $1000$ m$3$ containing $60\%$ hydrogen and $40\%$ ammonia is cooled

from $773$ K to $313$ K at $1$ atm pressure. Calculate the heat removed.

The Cp values in kcal$/$kmole K$,$ and T in K are:

for hydrogen Cp $=6\mathrm{.}90\mathrm{.}2$ x $103$ T $+0\mathrm{.}48$ x $106$ T$2$

for ammonia Cp $=6\mathrm{.}08+8\mathrm{.}81$ x $103$ T $1\mathrm{.}5$ x $106$ T$2$
