In the hydrodealkylation of toluene to benzene, the following reactions occur: C7H8 + H2 → C6H6 + CH4 2C6H6 ⇌ C12H10 + H2 Toluene and hydrogen are fed to a reactor in a molar ratio 1:5.80% of the toluene gets converted and the selectivity of benzene(defined as moles of benzene formed/moles of toluene converted) is 90%. The fractional conversion of hydrogen is_______________________?
