(a) Consider the reaction of hydrogen sulfide with methane, given below: 1 CH4(g) + 2 H2S(g) 1 CS2(g) + 4 H2(g) If CH4(g) is decreasing at the rate of 0.850 mol/s, what are the rates of change of H2S(g), CS2(g), and H2(g)? H2S(g)/t = _____mol/s CS2(g)/t = _____mol/s H2(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 595 torr/min, what is the rate of change of the total pressure in the vessel? Ptot /t = _____torr/min

Question

(a) Consider the reaction of hydrogen sulfide with methane, given below:

1 CH4(g) + 2 H2S(g)  1 CS2(g) + 4 H2(g)

If CH4(g) is decreasing at the rate of 0.850 mol/s, what are the rates of change of H2S(g), CS2(g), and H2(g)?



H2S(g)/t =  _____mol/s

CS2(g)/t =  _____mol/s

H2(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 595 torr/min, what is the rate of change of the total pressure in the vessel?



Ptot /t =  _____torr/min
