Explanation / Answer

part B

   average rate of disappearance of H3PO4 = - d[h3po4]/Dt

- d[h3po4]/Dt = 2*+d[P2O5]/dt

                = 2*2*10^-4

                = 4*10^-4 M

-d[h3po4]/Dt = 4*10^-4 M

2) -1/5d[Br-]/Dt = +1/3d[Br2]/Dt

  
rate of formation of Br2 = d[Br2]/Dt = 3/5*1.86*10^-4

          = 1.116*10^-4
