The decomposition of AB (g) to A(g) and B(g) is first order with respect to AB. If the rate constant for -1 the reaction is 0.530 hr answer each of the questions below. a) What is the rate of decomposition when [AB (g)]= 0.290 M? Rate: b) What is the half-life of the reaction (in hours)? t1/2 : 2 Ptot: M/hr hr c) If the initial pressure of AB (g) in the reaction flask is 0.210 atm, determine the pressure of all the gases, Ptot, after the reaction has proceeded for one half-life. atm
