2A+B----C+D is a reaction
Rate of the reaction = k[A]^2{B}^1/2
What is the order of the reaction if A is present in large excess. Guys its pretty urgent....

Question

2A+B---->C+D is a reaction
Rate of the reaction = k[A]^2{B}^1/2
What is the order of the reaction if A is present in large excess. Guys its pretty urgent....

chmvijay · Answer

order of the reaction is some of the exponential terms on the reactants 
can you answer now

anonymous · Answer

ya it needs to be 2.5 by addition, but as A is present in excess the answer may change, the answer given says 0.5

chmvijay · Answer

it is excess mean we cant tell accurately how much it can be 2 or three???
but more thatn 2.5 we can say definately

anonymous · Answer

@chmvijay  i dont know but the answer given here is 0.5, what do i do?

chmvijay · Answer

may be if A is large it wont count for the order of reaction and only counts is another reactant and it has value of 1/2 it is nothing but 0.5

anonymous · Answer

and moreover by A being in excess the reaction will take place on terms of B as it behaves like a limiting reagent....ya now i can get the whole picture.......
