(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)

(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

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.
