UPSEE Solved Model Paper 5

the reaction is
A + B → products
Order of A is 1 and the order of B is 1/2
The rate law for above reaction is
Rate r = K[A]1[B]

1

2

... (1)
Conc of both A and B are increased four times
Rate r = K[4A]1[4B]

1

2

= 8K[A]1[B]

... (2)
Dividing 1 and 2

r

r′

= K[A]1[B]

/ 8K [A]1[B]

= 8
So, rate increases by a factor of 8
