Hydrogen peroxide decomposes spontaneously into water and oxygen gas via a first-order reaction:

2 H2O2(l) → 2 H2O(g) + O2(g)

but in the absence of catalysts this reaction proceeds very slowly. If a small amount of a salt containing the Fe3+ ion is added to a 0.437 M solution of H2O2 in water, the reaction proceeds with a half-life of 17.3 minutes. What is the concentration of the solution after 10.0 minutes under these conditions? 

Top Answer

In the presence of a catalyst the rection becomes second order t1/2 = 1/(k x [A]o) 17.3 = 1/k... View the full answer
