Question

For a reaction, the dimension of the rate constant are the same as that of the rate of reaction, hence the order of reaction is :

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is A 0

Rate of a reaction is given by an equation, $r=k[A{]}^x$

Given:

The dimension of rate constant = Dimension of the rate of reaction

$r=k$

$k=k[A{]}^x$

$[A{]}^0=[A{]}^x$

$\therefore x=0$

Hence, option $\text{A}$ is correct.
