(a) Consider the reaction of hydrogen sulfide with methane, given below: 1 CH (9) + 2 H2S(9) 1 C52(9) + 4 H (9) If CH (9) is decreasing at the rate of 0.300 mol/s, what are the rates of change of H2S(o), CS2(9), and H2(9)? AH S()/At- mol/s molls ACS2(9/A - AH (9)/A - mols (b) The decomposition reaction given below: 2 IF(0) - 11() + 5F(0) is carried out in a closed reaction vessel. If the partial pressure of IF(o) is decreasing at the rate of 498 torr/min, what is the rate of change of the total pressure in the vessel? APror At- tort/min
