Aarey reactants will decrease with the time so issiliye uska graph will go down aur kisi particular time pe slope nikal uss graph ka is instantaneous rate of reactants but since it will come in negative as the slope is negative so to make the rate positive the negative sign is used -dR/dt As reactants decrease product rate increases so it has a positive slope so dP/dt the slope of the graph is instantaneous rate for products Aur instantaneous rate me dt tends to zero for very small interval so in instantaneous rate limit of dt tends to zero ?
