(a) Consider the reaction of hydrogen bromide with oxygen, given below: 4 HBr(g) + 1 O2(g) 2 Br2(g) + 2 H2O(g) If HBr(g) is decreasing at the rate of 0.650 mol/s, what are the rates of change of O2(g), Br2(g), and H2O(g)? O2(g)/t =___ mol/s Br2(g)/t = ___mol/s H2O(g)/t =___ mol/s

(b) The decomposition reaction given below: 2 IF5(g) 1 I2(g) + 5 F2(g) is carried out in a closed reaction vessel. If the partial pressure of IF5(g) is decreasing at the rate of 588 torr/min, what is the rate of change of the total pressure in the vessel? DELTAP /deltat = ____torr/min
