Which among the following reactions can be an example of a pseudo first order reaction?

What is the order of reaction if the unit of the rate constant is $s^{-1}$?

The given reaction $2NO + O_2 \to 2NO_2$ is an example of

Rate law for a reaction between $A$ and $B$ is given by $R=k[A]^{n}[B]^{m}$. If concentration of $A$ is doubled and concentration of $B$ is halved from their initial value,the ratio of new rate of reaction to the initial rate of reaction $\left(\frac{r_2}{r_1}\right)$ is
