Unidentified$1.$ Hydrogen is produced by the reaction of steam reforming of propane;

C$3$H$8+3$H$2$O$($v$)->3$CO$($g$)+7$H$2($g$)$

The water gas shift reaction also takes place in the reactor

CO$($g$)+$ H$2$O$($v$)->$ CO$2($g$)+$ H$2($g$)$

The feed to the reactor containing $100$ mol$/$h of propane and $500$ mol$/$h of steam

enters the reactor at $600\backslash$deg C$,$

a$.$ If the reactor operates adiabatically, the product stream emerges at $100\backslash$deg C and

propane conversion is $32\%.$ Find the product distribution for adiabatic

operation.

b$.$ If the product stream leaves the reactor at $800\backslash$deg C$,$ propane is converted

completely and extent of second reaction is $15$ mol$/$h$.$ What will be the amount

of heating gas having inlet and outlet temperatures of $1150\backslash$deg C and $850\backslash$deg C$,$

respectively $($The heat capacity of the heating gas: $0\mathrm{.}05$ kJ$/$kg$\backslash$deg C$).$
