Question

How will you provide the following information in a chemical reaction?

Catalyst.

Answer 1

1. Chemical Equation: A chemical equation is a shorthand method to describe the reaction taking place in terms of symbols and formulae of substances involved in the reaction.
2. Catalyst - A catalyst is a substance that speeds up the reaction without altering it.
3. Representation of Catalyst: The catalyst used in a reaction is provided above the arrow.
4. Example- The decomposition of hydrogen peroxide (${\mathrm{H}}_2{\mathrm{O}}_2$) takes place in presence of catalyst platinum ($\mathrm{Pt}$) to produce water (${\mathrm{H}}_2\mathrm{O}$) and Oxygen (${\mathrm{O}}_2$).

$$\begin{gathered} 2{\mathrm{H}}_2{\mathrm{O}}_2\left(\mathrm{s}\right)\stackrel{\mathrm{Pt}}{\to }2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right) \\ \mathrm{Hydrogen}\mathrm{Water}\mathrm{Oxygen} \\ \mathrm{Peroxide} \end{gathered}$$
