Answer:
The reaction is zero order with respect to B
Explanation:
The reaction given in the question is -
2A + 3 B ----> 2C + D
From , the above reaction the rate law is written as -
rate = k [ A ]²[ B ]³
where ,
k = rate constant
In the above equation the order is determined by the sum of the powers of the concentrations , i.e. 2 + 3 = 5 order , which never possible ,
Hence , in the question ,
The by changing the concentration of B , the rate does not change .
hence , the rate is independent of the concentration of B .
Therefore ,
The order with respect to B will be zero .
