Question

Rate expression of a chemical change is $-\frac{dx}{dt}=k{\left[A\right]}^2{\left[B\right]}^1{\left[C\right]}^0$. The order of reaction is:

• A. $3$
• B. $2$
• C. $1$
• D. $0$

Answer 1

Answer: (A)

$3$

$\frac{-dx}{dt}=K{\left[A\right]}^2{\left[B\right]}^1{\left[C\right]}^0$

The order of reaction is given as sum of the all the partial orders.

Hence order$=2+1+0=3$.
