Expert Solution

Fe3O4(s) + 4 H2(g) → 3 Fe(s) + 4 H2O(l)

- [Rate]Fe3O4 = - (1/4) [Rate]H2 = + (1 / 3 ) [Rate]Fe = + ( 1 / 4 ) [Rate]H2O

Question 1

rate of disappearance of Fe3O4   = ( 1 / 4 ) x  rate of disappearance of H2

= 7.1 / 4 =  1.775 M/s

Question 2

rate of disappearance of Fe3O4 =   (1 / 3 ) x [ Rate of appearance of Fe ]

Question 3

rate of appearance of H2O = ( 4/3 ) x  [ rate of appearance of Fe ] = ( 4/3 ) x 4.9 , M/s =  6.533 M/s

Question 4

Rate of appearance of Fe = 3 x [ rate of disappearance of Fe3O4 ]

Question 5

rate of appearance of H2O = 4 x [ rate of disappearance of Fe3O4 ]

Question 6

rate of disappearance of H2 = 4 x   [ rate of disappearance of Fe3O4 ] = 4 x  6.6 M/s =  26.4 M/s

Question 7

rate of disappearance of H2 = ( 4 / 3 ) [ rate of appearance of Fe ]

Question 8

rate of appearance of Fe = 3 x [ rate of disappearance of Fe3O4 ] = 3 x 7.4 M/s = 22.2 M/s

Question 9

rate of appearance of Fe = ( 3/4 ) x [  rate of appearance of H2O ] = ( 3/4 ) x  8.2 M/s =  6.15 M/s

Question 10

rate of disappearance of H2    = 4 x [ Rate of disappearance of Fe3O4 ]
