Given reaction :-
The balanced reaction is
(A) The rate of reaction is
Given:-
.
(B) rate of formation of P4 :
we have,
(C) rate of consumption of PH3
we have,
Note:-
Rate of reaction:- Rate of reaction is definded as the change in concentration of reactant or productper unit time.
Average rate of reaction:-
it is defined as the change in concentration of reactant or product divided by the time interval over which the change is occurs.
Consider a reaction:-
Hence,
For reactions involving different number of moles of substances the various reactants are consumed at different rates and various products are formed at different rates.
For example.
....(A)
here there are three different rates. However the rate of reaction must unique and must be same no matter which reactant or product is chosen to measure. To avoid the existence of multiple rates, the general rate of reaction is equal to the rate of consumption of a reactant or the rate of formation of the product divided by its coefficient in the balanced chemical equation.
Thus for reaction A.
