(a) Consider the combustion of butane, given below:

2 C4H10(g) + 13 O2(g) 8 CO2(g) + 10 H2O(g)

If C4H10(g) is decreasing at the rate of 0.300 mol/s, what are the rates of change of O2(g), CO2(g), and H2O(g)?

O2(g)/t = _____ mol/s

CO2(g)/t = _____. mol/s

H2O(g)/t = _____ mol/s

(b) The decomposition reaction given below:

1 SO2Cl2(g) 1 SO2(g) + 1 Cl2(g)

is carried out in a closed reaction vessel. If the partial pressure of SO2Cl2(g) is decreasing at the rate of 319 torr/min, what is the rate of change of the total pressure in the vessel? Ptot /t = _____torr/min
