Not even sure what Aris Method is so please work out completly. Use the Aris method to determine the number of independent reactions in the following system.

$4N{H}_3+5O_2$harr$4NO+6H_{2}O$

$4N{H}_3+3O_2$harr$2N_2+6H_{2}O$

$4N{H}_3+6$NOharr$5N_2+6H_{2}O$

$2NO+O_2$harr$2N{O}_2$

$2NOharr{N}_2+O_2$

$N_2+2O_2$harr$2N{O}_2$

For the sake of uniformity, number the chemical species as follows:
