Consider the chemical reaction P Q , being carried out in two different vessels X and Y with 1 litre solution of P in each of them. The reactions are started with 1 mole of P in X and 2 moles of P in Y . Further P is added continuously to both the vessels at the rate of 1 mole/sec during the first two seconds only. It is observed that [ P ] (concentration of P ) remains constant at the initial value in both the vesse
