HI  +  aHNO2   -->   bH2O  +  cNO  +  dI2

H  : 1 + a   -->   2b ......................(1)

I  :  1 = 2d  .................................(2)

N  :  a = c...................................(3)

O  :  2a  =  b + c  ........................(4)

 

(2) : d = 1/2 ..............................(5)

(3) dan (4)  :  a = c ; 2a = b + c

                                       2c = b + c

                                       b = c .........(6)

a = b = c ...................................(7)

(1) dan (7)  :  1 + a = 2b

                         1 + a = 2a

                                a = 1

masing-masing koefisien dikali 2

2HI  +  2HNO2   -->   2H2O  +  2NO  +  I2
