If HEr(g) is decreasing at the rate of 0.820 mol/s, what are the rates of change of O2(g),Br(g(g), and H2O(g) ? O2(g)/t=B2(g)/t=H2O(g)/t=Xmol/smol/s (b) The decomposition reaction given below: 3NO(g)1N2O(g)+1NO2(9) is camied out in a closed reaction vessel. If the partial pressure of NO(g ) is decreasing at the rate of 83a torrimin, what is the rate of drange of the tatal pressure in the vessel? Ptot/t= xtor/min Consider the following reactions 4HB(g)+O2(g)2H2O(g)+2BC(g) (a) The rate law for this reaction is first order in HBr(g) and first order in O)(g). What is the rate law for this reaction? Rate =k[HBr(g)][O2(g)] Rate =k[HBr(g)]2[O2(g)] Rate =k[HBr(g)][Oj(g)]2 Rate =k[HBr(g)]2[O(g)]2 Rate =k[HBr(g)][O2(g)]3 Rate =k[HBr(g)]4[O(g)] (b) If the rate constont for this reaction at a certain temperature is 8710 , what is the reaction rate when [hErio)] = 0.00550.M and [0 j (0)]=0.40615M
