Write general equation of reaction and explain -what is order of reaction?which is its value?

Answer»

Solution :General reaction:aA+bB`to`cC+dD
The differential rate expression of reaction is as under.
Rate=`-(d[R])/(dt)=k[A]^(x)[B]^(y)`
Where ,the value of x and y are DETERMINE experimentally which are same or not a and b.
where x and y indicate how sensitive the rate is to the change in concentration of A and B.
(i)x represent the order with respect to the reactant A.
(ii)y represent the order with respect to the reactant B.
(III)(x+y)=Overall order of a reaction .
Order of reaction:The sum of power of the concentration of the reactants in the rate law expression is callled the order of that CHEMICAL reaction.
Order of a reaction can be 0.1,2,3 and even a fraction ,these value are ALWAYS determined by experimentally.
