Moderate reactions among the following.

Decomposition of ${\mathrm{H}}_2{\mathrm{O}}_2$ an inversion of cane sugar is example of Moderate reactions.

${\mathrm{HCl}}_{\left(\mathrm{aq}\right)}+{\mathrm{NaOH}}_{\left(\mathrm{aq}\right)}\to {\mathrm{NaCl}}_{\left(\mathrm{aq}\right)}+{\mathrm{H}}_2{\mathrm{O}}_{\left(l\right)}\to \mathrm{fast} \mathrm{reaction}$

${\mathrm{C}}_{\left(\mathrm{s}\right)}+{\mathrm{O}}_{2\left(\mathrm{g}\right)}\stackrel{\mathrm{room} \mathrm{tem}}{\to } {\mathrm{CO}}_{2\left(\mathrm{g}\right)}\to \mathrm{slow} \mathrm{reaction}$
