(a) Conskder the combustion of butane, given below: 2C4H10(g)+13O2(g)8CO2(g)+10H2O(g) If C4H1O(g) is decreasing at the rate of 0.720 mol/s, what are the rates of change of O2(9),CO2(9) and H2O(9)? ? O2(g)/t=CO2(g)/t=H2O(g)Vat=mol/smolssmol/s (b) The decomposition reaction glven below: 2N2O5(g)4No2(g)+1O2(9) is carried cut in a closed reactoon vessel. If the partial pressure of N2O5(a) is decreasing at the rate of 157 torr/min, what is the rate of change of the total pressure in the vessel
