Specifying reaction information

Hitting Aforf button and clicking on New , we have the following forms (see Figures 2.47(a)
and (b)) for reaction number 1 (2C 6H6 -> C12H10 + H2). Since the reaction rate constants
are defined with respect to benzene , we convert the stoichiometric coefficient of benzene
the reactions are second-order.
to unity for both the reactions . Obviously ,
