The gas - phase reaction between NO and `Br_(2)` is respresented by the equation `2NO_((g)) + Br_(2(g)) to 2NOBr_((g)` (a ) Write the expressions for the rate of consumption of reactants and formation of products. ( b) Write the expression for the rate of overall reaction in terms of rates of consumption of reactions and formation of products. |

Answer» Given : `2NO_((g)) + Br_(2(g)) to 2NOBr_((g))` (a ) Rate of consumption of NO at time `t= - (d[NO])/(dt)` Rate of consumption of `Br_(2)` at time `t = (- d[Br_(2)])/(dt)` Rate of formation of NOBr at time `t= (d[NOBr])/(dt)` ( b) Rate of reaction `= - (1)/(2) (d[NO])/(dt) = (-d[Br_(2)])/(dt) = (1)/(2) (d[NOBr])/(dt)` |
