The reaction that governs steam reforming of butane are as follows:

$C_4{H}_{10}+H_{2}Oharr{C}_3{H}_8+CO+2H_2$

$C_3{H}_8+H_{2}Oharr{C}_2{H}_6+CO+2H_2$

$C_2{H}_6+H_{2}OharrC{H}_4+CO+2H_2$

$C_2{H}_4+H_{2}OharrC{H}_4+CO+H_2$

$C{H}_4+H_2$OharrCO$+3H_2$

$CO+H_{2}OharrC{O}_2+H_2$

Consider initially that you have $87kg$ of butane. If the steam is available in surplus, how much is

the expected production of hydrogen? How much steam will be consumed?
