Problems in Class Chapter 13: 1. The initial concentration of H2O2 is 0.1108 M, and 12 seconds later the concentration is 0.1060 M. What is the initial of this reaction expressed in M/s and M/min? 2. Consider the gas phase reaction : 4 PH 3 (g) P 4 (g) + 6 H 2 (g) If the instantaneous rate of formation of H 2 (g) is 2.1 x 10 -3 mol L -1 s -1 , what is the instantaneous rate of disappearance of PH 3 ? 3. #32 from book 4. The rate law for the reaction CH 3 CHO(g) → CO(g) + CH 4 is 3/2 order in the reactant. At a pressure of CH 3 CHO = 0.416 atm the rate is 3.79 x 10

Unformatted text preview: -3 atm/sec. Find k and its proper units. 5. Book Problem #40 6. Consider the reaction 2 H 2 O 2 ( l ) 2 H 2 O( l ) + O 2 (g) Assume that this reaction follows first-order rate kinetics and that its half-life is 10.0 minutes. How long would it take for 80.0% of an original H 2 O 2 sample to decompose? 7. The activation energy of a reaction is 84.9 kJ/mol and the frequency factor is 3.98 x 10 9 L/mol sec.
