Question

For the following reaction:
$A+2B\rightleftharpoons C$
The rate law was found to be:
$rate=k[A{]}^2$
What is the overall rate order for this reaction?

• A. $0$
• B. $1$
• C. $2$
• D. $3$

Answer 1

The correct option is C $2$

Rate $=k[A{]}^2$

The overall order of a reaction is the sum of the powers of the concentration terms in a rate law of equation.

Therefore, an overall order is 2.

Therefore, the correct answer is $\left(C\right)$.
