QAIPMT-2005-Ch-2512: NEET 2005 Chemistry - Class 12 AIPMT-2005-Ch-2512 Solution: The rate of reaction between two reactants A and B decreases by …
The rate of reaction between two reactants A and B decreases by a factor of 4 if the concentration of reactant B is doubled. The order of this reaction with respect to reactant B is
Multiple Choice Options
- A 2
- B
- C 1
- D
Step-by-Step Verified Solution
A + B _ Product
Rate _ [A] x
[B] y .......(1)
The rate of the reaction decreases by a factor of 4 if
the concentration of reactant B is doubled.
r 4 _ [A] x
[2B] y ......(2)
From equation (1) and (2), we get
( 1 2 ) y = 4
_ y = -2
_ Order of this reaction with respect to reactant B is -2.
