(a) Consider the reaction of hydrogen bromde with oxypen, 9 ven below: 4HBr(g)+1O2(g)2E(2(g)+2H2O(g) O2(g/At=cr2(g)/At=H2O(g)/At=mol/smol/smol/s (b) The decomposition reaction given belaw: 3NO(g)1NO(g)+1NO2(g) is carried out in a closed reaction vessel. If the partial pressure of No( 9) is decreasing at the rate of 556 toerimin, what is the rate of change of the total pressure in the veusel? Ptok/t= Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium the forward rate equals zero. At equilibrium the forward rate constant equals the reverse rate constant. At equilibrium all reactions stop. As a reaction proceeds forward toward equilibrium the reverse rate rises. As a reaction proceeds backwards toward equilibrium the reactant concentrations rise
