$(20$ pt$)[$Chemical production$]$ Toluene reacts with $H_2$ to form benzene and methane, but a side

reaction occurs in which toluene and hydrogen also react to form a by$-$product diphenyl

$(C_{12}{H}_{10})($along with methane$).$ In the process the makeup hydrogen is added to the recycle

stream to make the ratio of $H_2$ to $C{H}_{4}1$ to $1$ before the gas enters the mixer. The ratio of $H_2$ to

toluene entering the reactor at $G$ is $4H_2$ to $1$ toluene. The conversion of toluene to benzene on

one pass through the reactor is $80\%,$ and the conversion of toluene to the by$-$product diphenyl

is $8\%$ per pass. Calculate the molar flows $R_G$ and $R_L.$

I need help with the Degree of Freedom Analysis and creating an extent of reaction table
