Question

$A+B\to$ product, $\frac{dx}{dt}=k{\left[A\right]}^a{\left[B\right]}^b$
If $\left(\frac{dx}{dt}\right)=k$ then order is:

• A. $4$
• B. $2$
• C. $1$
• D. $0$

Answer 1

Answer: (D)

Given $\frac{dx}{dt}=k{\left[A\right]}^a{\left[B\right]}^b$
and if $\frac{dx}{dt}=k$
then $a+b=0i.e.$ zero order reaction.
