Consider the reaction: 2 H 2 O 2 (aq) 2 H 2 O(l) + O 2

Question:

Consider the reaction:

2 H2O2(aq) → 2 H2O(l) + O2(g)

The graph shows the concentration of H2O2 as a function of time.Concentration (M) 1.2. $1.0- 0.8 0.6 0.4- 50.2 [HO] 0- 0 10 20 30 40 50 60 70 80 Time (s)

Use the graph to calculate each quantity:

a. The average rate of the reaction between 10 and 20 s 

b. The instantaneous rate of the reaction at 30 s 

c. The instantaneous rate of formation of O2 at 50 s 

d. If the initial volume of the H2O2 is 1.5 L, what total amount of O2 (in moles) is formed in the first 50 s of reaction?
