Question

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 0.510 mol/s, what are the rates of change of O2(g), Br2(g), and H2O(g)?

change in O2(g)/change in t =

change in Br2(g)/change in t =

change in H2O(g)/change in t=

(b) The decomposition reaction given below:

2 N2O5(g)  --->4 NO2(g) + 1 O2(g)

is carried out in a closed reaction vessel. If the partial pressure of N2O5(g) is decreasing at the rate of 608 torr/min, what is the rate of change of the total pressure in the vessel?

change in Ptot /change in t =
