The rate of the given reaction has to be expressed in terms of Δ [ N 2 O 2 ] . Concept Introduction: Rate of the reaction can be expressed in terms of change in concentration of reactant and products by multiplying the reciprocal of the corresponding stoichiometric co-efficient to that. When the rate is expressed in terms of change in reactant concentration, a minus sign has to be given. Since change in time will be a positive quantity and reactant concentration decreases with time change in concentration of reactant will be negative. So in order to make the rate a positive quantity negative sign is given. But if the rate is expressed in terms of change in concentration of products, which is a positive quantity, no need of negative sign in the rate expression.
