Question

For a reaction $2A+3B\to$ Products,

the rate law expression is given by rate $=K\left(A{)}^1\right(B{)}^2$. The order of the reaction with respect to $A,B$ and overall order of reaction are:

• A. $2,1,3$
• B. $1,2,3$
• C. $0,1,2$
• D. $2,1,0$

Answer 1

The correct option is B $1,2,3$

The rate law expression is $=K\left(A{)}^1\right(B{)}^2$.

The order of the reaction with respect to A and B is 1 and 2 respectively.

The overall order of the reaction is $1+2=3$.

Hence, the correct option is $\text{B}$
