Question:

(A) For reaction (20.3), determine 

(a) The instantaneous rate of reaction at 2400 s and 

(b) [H2O2] at 2450 s. 

Assume that the instantaneous rate of reaction at 2400 s holds constant for the next 50 s.


Reaction (20.3)

+12/0(8) H,Oz(aq)  H_O(1) + (20.3)

(B) Use data only from Table 20.2 to determine [H2O2] at t = 100 s. Compare this value with the one calculated in Example 20-2(b). Explain the reason for the difference.


Table 20.2

TABLE 20.2 Decomposition of HO2-Derived Rate Data IV Time, s 0 400 800 1200 1600 2000 2400 2800 || At, s 400


Example 20-2(b)

From the data in Table 20.2 and Figure 20-2 for the decomposition of H2O2, determine

(b) [H2O2]t at t = 100 s, assuming that the initial rate is constant for at least 100 s.
