Order of a Reaction

For the following elementary reaction, determine its order of reaction and the dimensions of the rate constant:

$2\text{NO}\left(\text{g}\right)\to {\text{N}}_2\text{O}\left(\text{g}\right)+\frac{1}{2}{\text{O}}_2$

For a reaction, $\mathrm{A}+2\mathrm{B}\to \mathrm{C}$, the rate is given by $+\frac{\mathrm{d}\left[\mathrm{C}\right]}{\mathrm{dt}}=\mathrm{k}\left[\mathrm{A}\right]\left[\mathrm{B}\right]$, hence, the order of the reaction is:

Order of a reaction is the sum of exponents of _____ in the rate equation.

Order of a reaction with rate constant ${\text{mol}}^{-1}{\mathrm{L}}^{}{\mathrm{s}}^{-1}$ is :

Rate constant and rate of a reaction have the same units for reactions of _____ order.

What is the order for the following reactions?
${\mathrm{CHCl}}_3 \left(\mathrm{g}\right) +{\mathrm{Cl}}_2 \left(\mathrm{g}\right) \to {\mathrm{CCl}}_4 \left(\mathrm{g}\right) +\mathrm{HCl} \left(\mathrm{g}\right)$, rate$=\mathrm{K}\left[{\mathrm{CHCl}}_3\right] [{\mathrm{Cl}}_2{]}^{1/2}$

The rate law for the gas-phase reaction $2\mathrm{NO} \left(\mathrm{g}\right)+ {\mathrm{O}}_2 \left(\mathrm{g}\right) \to 2{\mathrm{NO}}_2 \left(\mathrm{g}\right)$ is rate $=\mathrm{K}[{\mathrm{NO}}_2{]}^2 [{\mathrm{O}}_2].$ What is the order of the reaction with respect to each of the reactants and what is the overall order of the reaction?

Determine the rate law and the rate constant for the reaction.

In a reaction between $\mathrm{A}$ and $\mathrm{B}$, the initial rate of reaction $\left({\mathrm{r}}_{\mathrm{o}}\right)$ was measured for different initial concentration of $\mathrm{A}$ and $\mathrm{B}$ as given below:

What is the order of the reaction with respect to $\mathrm{A}$ and $\mathrm{B}$?

Suppose in a chemical reaction $\mathrm{A}\to \mathrm{B}$, it is found that the rate of the reaction doubles when the concentration of $\mathrm{A}$ is increased four times. The order of the reaction with respect to $\mathrm{A}$ is

It is true that :  

(1) A zero order reaction is a single step reaction.  

(2) A second order reaction is always a multistep reaction.  

(3) A first order reaction is always a single step reaction.

(4) A zero order reaction is a multistep reaction.

In a reaction, the time required to complete half of the reaction was found to increase 16 times when the initial concentration of the reactant was reduced to 1/4th. What is the order of the reaction?

The rate of the reaction, $\mathrm{A}+\mathrm{B}+\mathrm{C}\to$ Products, is given by

$\mathrm{r}=-\frac{\mathrm{d}\left[\mathrm{A}\right]}{\mathrm{d}\mathrm{t}}=\mathrm{k}\left[\mathrm{A}{]}^{\frac{1}{2}}\right[\mathrm{B}{]}^{\frac{1}{3}}[\mathrm{C}{]}^{\frac{1}{4}}$

What is the order of a reaction which has a rate expression $\mathrm{r}\mathrm{a}\mathrm{t}\mathrm{e}=\mathrm{k}{\left[\mathrm{A}\right]}^{3/2}\mathrm{ }{\left[\mathrm{B}\right]}^{-1}$

The rate of the reaction,

$3\mathrm{A}+2\mathrm{B}\mathrm{ }\to \mathrm{ }\mathrm{P}\mathrm{r}\mathrm{o}\mathrm{d}\mathrm{u}\mathrm{c}\mathrm{t}\mathrm{s}$

is given by the rate expression :

$\mathrm{R}\mathrm{a}\mathrm{t}\mathrm{e}=\mathrm{k}\left[\mathrm{A}\right]{\left[\mathrm{B}\right]}^2$

If $\mathrm{A}$ is taken in excess, the order of the reaction would be :

If a certain reaction is first order with respect to $\mathrm{A},$ second order with respect to $\mathrm{B}$ and zero order with respect to $\text{C}$ then what is the order of reaction?
