Explanation / Answer

H2O2 = 0.1 M given

H2O2 =0.1-initial [H2O2]

1. H2O2 =0.1-0.005=0.095 M

2. H2O2 =0.1-0.005=0.095 M

3. H2O2 =0.1-0.005=0.095 M

4. H2O2 =0.1-0.01=0.09 M

5. H2O2 =0.1-0.02=0.08 M

Rate

1. H2O2 / t=0.095/1457.4=6.518*10-5 M/s

2. H2O2 / t=0.095/708=1.34*10-4 M/s

3. H2O2 / t=0.095/583=1.6310-4 M/s

4. H2O2 / t=0.09/267=3.37*10-4 M/s

5. H2O2 / t=0.08/89=8.99*10-4 M/s
