In acidic medium, the rate of reaction between ${\mathrm{BrO}}_3^{-}$and ${\mathrm{Br}}^{-}$ is given by the expression $-\frac{\mathrm{d}\left[{\mathrm{BrO}}_3^{-}\right]}{\mathrm{dt}}=\mathrm{k}\left[{\mathrm{BrO}}_3^{-}\right]\left[{\mathrm{Br}}^{-}\right]{\left[{\mathrm{H}}^{+}\right]}^2$. What does it mean?

$\mathrm{A}+\mathrm{B}\to \mathrm{C}$

Rate is expressed in $\mathrm{mol} {\mathrm{L}}^{-1}{\min }^{-1}$

Select the incorrect options regarding the order.

For the chemical reaction,

$\mathrm{A}+\mathrm{B}+\mathrm{C}\to \mathrm{E}$

The rate of reaction is doubled when the concentration of $\mathrm{B}$ is doubled, and when the concentration of both $\mathrm{A}$ and $\mathrm{B}$ is doubled, the rate becomes doubled and when the concentration of both $\mathrm{B}$ and $\mathrm{C}$ are doubled the rate becomes quadrupled.

Which of the given statement(s) is/are correct?

For a 1^st order reaction:

$2{\mathrm{N}}_2{\mathrm{O}}_5 \left(\mathrm{g}\right)\to 4{\mathrm{NO}}_2 \left(\mathrm{g}\right)+{\mathrm{O}}_2 \left(\mathrm{g}\right)$
