In a reaction,

$\mathrm{aA}+\mathrm{bB}⟶\mathrm{cC}+\mathrm{dD}$

rate $=-\frac{1}{\mathrm{a}}\frac{\mathrm{d}\left[\mathrm{A}\right]}{\mathrm{dt}}$, the $-\mathrm{ve}$ sign in it represents

For the reaction, $2{ \mathrm{N}}_2{\mathrm{O}}_5⟶4{\mathrm{NO}}_2+{\mathrm{O}}_2$

In a certain reaction shown below, $4\mathrm{A}+2\mathrm{B}⟶3\mathrm{C}$

If rate of formation of $\mathrm{C}$ is $9.6\times {10}^{-2} \mathrm{mol}/\mathrm{Ls}$, what will be rate of reaction?

For the reaction, ${\mathrm{H}}_2{\mathrm{O}}_2+2{\mathrm{H}}^{+}+3{\mathrm{I}}^{-}⟶{\mathrm{I}}_3^{-}+2{\mathrm{H}}_2\mathrm{O}$
